@Alan Heagerty Why not? You shouldn't have to stud it to begin with but its just extra insurance if you do. And no, you are just using stronger hardware to hold the heads to the block. No tune needed.
You said yourself truck runs strong and feels powerful I wouldn't worry about a dyno number.mine will haul ass when I put the hammer down that's all that matters.
nice truck, be a great 5.9 cummins project. My Truck has the 7.3 Turd, but super dependable ( as long as a cam sensor and 10 mm wrench is in the glove box)
like others have said verify your truck is 100% , I would stop messing with tunes I would reload the the stock file,Dyno the truck bone stock,if it's low on power than you know for sure you have a problem. Also like others have said check the exhaust system even the smallest leak before the turbo will kill your power,I also check your fuel pressure at your filter housing make sure your low pressure pump is performing properly looks like your trucks fairly old could have a plugged sock in the fuel tank or a weak pump.The turbo chargers are known to crack the variable vane ring and they were out from lots of city driving,not sure when it was bulletproof but it's normal procedure to pull the turbo clean it and check those parts for wear, you even said that you're having slow spool up that's one of the symptoms of a worn or sticking VGT set up
My 6.0 does that sometimes (lags before it kicks in) I'm curious on your results of the evp sensor. It doesn't happen all the time though. I have heard good thing about replacing the turbo compressor wheel. I want head studs before I replace it. Keep up the vids man!
its usually not the ebp sensor itself usually the tube is clogged with carbon. vanes could be sticking or the unison ring worn. what people fail to realize is the engines are usually rated at the flywheel and not to the tires. your tires and lift added tothat id say 295 to the ground is about right for the minor mods you have. stock tune you might make 250 to the ground. i believe typical drivetrain loss is 15%.
okay, so to start fix the ebp, when it acts up it will scew your 5v ref that all your other sensors use🤔 like icp, map, maf, ect, and so on. this will make all the readings to the pcm inacurate, does that make sense? also I can personally vouch for the looney wild tune. I have been running it for 2 yrs as my DD tune. I pull trailers, drag race, and travel with this tune and it always delivers. and like you I have like 4 other tunes from other companies (they shall remain nameless), so I know how the truck perfomes with other tunes. the mileage is great I get 15.5 mpg city and I have a heavy foot. the transmission shifts awesome, and the truck ran 14.5 with the same setup you have (mine is a 4 door though 8300lbs on the scales)
Just bought an 06 F250 with 98k on it and did all the upgrades to the high pressure oil system. Truck had been sitting a lot over the last couple years according to the original owner. While I had it down I cleaned to turbo up real good, it had some pretty significant rust build up that was binding the unison ring. Cleaned it all up put it together and vgt is still doing stupid stuff working when it wants to or not at all. Turns out the connection was corroded at the ebp sensor. A little contact cleaner and a wire brush and now we're in business.
Check exhaust leaks between the Manifold and turbo, check and clean the back pressure sensor tube, make sure the VNT ring and veins are not stuck in suet.
You said the turbo is not spooling up fast enough . I would check the unison ring on the turbo and the mechanism that operates it becuse if the vains are stuck open that would cause your turbo not to spool up fast and low power . I Wonder do you have any check engine lights. Also please check fuel pressure make sure its up to spec .... just throwing shit against the wall to see what sticks lol ... good luck
You could try a flow test on injectors at a ford dealer , check the voltage on the FICM, fuel pressure and make sure the turbo is clean . Like other guys are saying big wheels rob power.
My SPD tune makes less boost than my other tunes but i ran a 13.8 at 98mph on stock turbo and 37" tires. they are good tunes for sure. fastest 1/4 i did with stock turbo
I work on ford diesels every day. Its my job. make sure there are no exhaust leaks where the up pipes go into the turbo. If there is, the vgt learn process will not complete. We have the same issue pretty often. without the vgt learn process, the whole truck will become gutless. just something to look at!
A few things: I've watched your videos, but havn't heard if you've regeared (at least the rear end)? running 35 inch tires, you should be at least at 4.10 gears to get back to 'kinda' stock ratios; this will make a HP difference. Don't brush off bad sensors, they will tell the computer to gimp the whole truck sometimes. I would clean them or replace the ones that show errors. Get a quick buzz test done on your injectors to see if any are bad. The tuner will throw a lot of power into the truck and make everything feel okay, turn it off or run it in a stock setting to see if something sounds/feels off. I work on my 7.3L's, stock and tuned, so I'm just trying to help with the difference some of this stuff will make. Good Luck!
Boost leak would be my bet. Get a vacuum test done and see if it is loosing boost. It'll show its building boost and then leak causing the boost gauge to be reading wrong. My truck had a similar problem. The veins in the turbo were not opening and closing like they should be and that could also be what is wrong with yours. Also check out gearhead tunes, best tunes on the market.
This might sound stupid, but check your fuel pressure. If it's running lean, it takes longer to build boost because there's not as much exhaust pressure.
Try a different dyno. Ive watched my buddys truck dyno 550 on this dyno and then 210 on another. Difference between the two one was loaded and one wasnt
The rule I run is don't spend money on your truck because your truck will spend your money it's just a matter of time. What I don't understand is why are you trying to make power in a diesel? not like you work the truck
allhail6.0 I'd say read up on it first but it's really easy to clean those ebp sensors as long as your careful. mine went bad on a 3xxx mile trip and I was able to take it out and clean it and nurse it the rest of the trip. just a thought. but ebp sensors DO Rob a lot of power when they're going bad! just because the turbo sounds good doesn't mean the fuel mixture is good. the ebp sensor controls ALL OF THAT!
allhail6.0 also scheids diesel extravaganza in Tere Haute Indiana is coming up end of August! it's a great time and they'll have a dyno if you can't get to one soone! I'll be there with my 6.0 just look for a chase 420 and USMC sticker on the back window of a white 6.0!
you need to get a contribution test why do people f*** with the 6.0 so much I have a stock 6 o never touched never studded runs perfect, 265,000 it rips stock, I'm a dirt bike racer it feels fine stock, people stop fucking with your trucks if you want them to run forever, and read your service manual on your vehicle... maintenance maintenance maintenance
Dude, I'd bet that if it's not your tune then you're having some kind of fuel issue. The 6.0 is known for problematic injectors and even one not working right can cause issues like yours. I'd make sure the engine is running right on a mild tune before dropping $$$ on random tunes hoping to fix the problem.
Lift kit won't rob too much hp on a Dino but it will make a little difference. Honestly I wouldn't expect this truck to make much more hp than stock because it only has exhaust and intake mods which don't add much horsepower and the tuner doesn't add much hp either, unless you have engine mods to compliment the tune. Bigger tires, lift kit, and engine wear are drawing down the horsepower to what ford says it should have stock
Tuners are the worst thing for any diesel Ford I've been doing ford for 38 years every single one that has the problem has a tuner in them leave them alone they'll run forever
Gearing, bud. Horsepower is a DERIVATIVE of torque. When you're dyno'ing wheel horsepower you're measuring wheel torque. When you increase your tire size you NEED to gear the differential to compensate. Gear the diffs to 4.30s or 4.56s instead of the factory 3.73 and you'll notice a MASSIVE increase in wheel horsepower, because of the increase in multiplicative torque of the gearing.
Glenn Conner it's also measuring speed, so gearing doesn't really matter on a dyno. Taller gears will deliver less torque to the wheels, but more speed, so the Hp will be the same.
Then this kind of car won't run for shit. It's not your average oil burning Gasser you can run till it falls apart 1 part fails on diesels and your in for quite the work and money but it is necessary if you have to work it hard besides I plan to own my cars till the engine falls off or it rusts so bad the frame breaks
You stomp the shit out of it everywhere you go from what I’ve seen. Your always going to be putting money in it. I have a Harley Davidson 6.0 never had any problems..it’s bone stock. There not meant to be tuned if they where ford would have done it.
Dusty Boy too much hate on 6.0 like if any other car never had an issue and most people bash on Ford when it is a VT365 International engine Ford built the truck and transmission they never built the engine
People that tune, lift, and put oversized tires on their trucks are stupid, the vehicles was NOT designed for it, you guys never even think about the differential.
It's not about problems, it's about ratio. When you increase the tire size you need to change the diff gears to compensate, or else it'll SUCK power, as evidented by this video. 35s need a 4.10. 37s need a 4.30. 38-40 needs a 4.56 42 needs a 4.88 44 needs a 5.13 Etc...... Otherwise all the power is lost as heat in the drivetrain, particularly the torque converter.
Nathaniel Clark while some people who modify their vehicles are stupid it's not fair to say everyone is. They just have different ideas for what they want in a truck. OEMs need to design their trucks for what the average buyer wants and needs. Some people want more power or off-road capability and they're willing to sacrifice a little fuel economy, reliability, and/ or money to get it. That doesn't make them stupid. Plus, sometimes OEMs make mistakes and an aftermarket part comes out to fix the problem.
Glenn Conner technically bigger tires do not suck a lot of horsepower, they just need more torque to turn them because they have a larger diameter. Also, they change the engine speed to vehicle speed ratio which sometimes causes the engine speed to be too low for the load. Yes they do have slightly higher rolling resistance which robs some power, but changing the gears doesn't being that power back. Higher ratio gears simply increase the torque multiplication in the differential and allow the engine to run at a higher rpm where it can make more hp.
Truckfan 87 6.0 is a wonderful engine to tune but definitely not a budget friendly tuner vehicle these go heavy on the wallet I'm saying from stock to stud minimum $5k Duramax have overheat issues with the crappy cooling system as we own one good just doing light loads but 10k pounds or more often redo the cooling system cause it has the pos transmission cooler built in to the radiator
