How To P59 Gen 3 Tuning + Truck Norris Tune Review 

Thanks for tip on the other fuses. I pulled radio only and built a bench unit because of it. 03' Sierra 6.0

Great information, great explanations!! Thanks for helping us learn!

Thank you for another great video

Thanks for the great info, I pretty much work on just Gen 3 and 4, new to tuning and never heard of removing those fuses. Might be why I have bricked a spare PCM, keep them coming

Gorgeous wheels!!! I'm running a set of snowflakes gloss black on 285/50r20s.

Kudos for the no BS diag on the TB and not band-aiding it. Interested to see the change after the new TB and tuning.

Great video, new subscriber. I'm learning to tune my own trucks so any information I can get helps

I've had that same long crank/ pop issue with a bad fuel pump too.

I have 2006 Silverado with a 6.0 with the truck Norris cam in it. I have that same issue with a long start but only after it’s hot. Starts up fine cold and hard to start when hot. All my sensors were replaced with acdelco. Still have the same issue

I am with u on the bench harness those are iffy

Love the content man, I just picked up a Mpvi3 a couple months ago and have been learning since. Also couldn’t the delayed start also be a fuel pump check valve failure, my truck I have to wait on ignition for a couple seconds then it will start. If I just put the key and and turn it over it does exactly what that truck did, and if I turned it right after starts right up. Not saying your wrong either. :)

I have t pull the radio fuse in my truck every time I want to write to it. It reads fine, just won't write. I tuned one the other day and had to pull a bunch of fuses to get it to write after it failed the first time Got lucky !

Just have a question, so I’m pretty familiar with ls engines and how they operate and run, but which cam would you say is the best for daily driving in a 1500 truck but also still wanting some power added and to be reliable?

In addition to my last comment, my 6.0 has tbss intake and an LS3 throttle body with the 42lbs injectors from a 8.1 marine engine so I could keep my factory injector plug

Was thinking of doing on my 04 gmc 5.3 the stage 4 223 cam but was wondering if I went with the 212 truck Norris, would I be disappointed ? And if I was going with the 223 what else would I need to upgrade?

Matt, if we are tuning these p59 computers and just writing new files, what precautions do we need to take to ensure “bricking” doesn’t happen.

can you show how to make a smaller cam chop like a big cam thanks

Been learning alot from your videos but probubly would take me forever to tune half as good. Was wondering how much you would charge to make and sent me a tune file for a 225 cam, 3000 stall, long headers, cold ram air intake, stock new 4l60e, engine is an lm7. That is if you do offer remote tuning.

what size wheels and tire size tires do you have on the truck ?

That's hilarious. My green plug on my ECU was filled with oil. Got an lm4 out of an 03 trailblazer ext from someone on Facebook marketplace and it came with the harness and PCM and TAC module and everything. I ended up going with a standalone harness from HPI. Anyways. I unplugged the PCM and the green plug was filled with oil. I was very curious how that even happened. I've started my engine a few times on the stand and the oil pressure sensor isn't leaking or anything. Interesting though.

Man where are you? Do you do mail in tunes? Have a 06 rcsb that has been v6 to v8 swapped with a summit torkinator cam. everything else stock. How can i get in touch with you, would love a tune from you if possible

If battery voltage is the concern, why not just put a battery maintainer on when you’re KOEO? Or is it an issue with voltage regulation KOER?

I’ve bricked an ecu before I wonder if just hooking up a charger to the battery while reading would help. I did that with a handheld tuner and fixed it

Do you have any experience with the Zero Gravity TCM 2650 Gateway? Im doing a 6L80 in a 2005 GMC Sierra and I have some questions and how torque management is going to work with this combo.

I have tuned my p59 in the truck on high speed like 13 times now, aftermarket radio

hate to ask but what wheels and tires???

Hey man I need help I have a 2005 gmc Sierra cammed and good heads and built 65e, it’s on a mail order base tune currently but for some reason when I start it in the morning it drives perfectly fine but when the thermostat opens and gets to temp my truck will shift to 2nd gear and stay in 2nd no matter what, only way around it is to pull over and restart it then it shifts super hard but shifts through all the gears like it should except I can’t get it to stay in 1st gear over like 10 mph even if I have it in “1”on the column shifter it will just shift to 2nd which sucks for burnouts because it will light up in 1st gear for 1 second then shift to 2nd where as before I could spin them through 1st for 20feet then shift to 2nd and keep spinning But only thing I could think of is my battery not giving the tranny enough power because I don’t think the battery I have is the right size but currently I have no codes except for my cats being gone. Sorry so long thanks for your help if you see this man.

So you don’t have to have a bench harness for a p59 it’s just quicker?

Check the injectors

I wanna learn how to tune. I have truck norris cam and 😂 maybe I'll get a 5.3 and just hone that and get 799 head and ss trailblazer intake.

Need a tune for my truck how can I contact you
