2017 Chevrolet Colorado 2.8 Duramax Tuned and Deleted Sound First Start 

Thats because the factory downpipe is still on the truck. I have an aFe downpipe installed now (im in Canada), stay tuned for a sound comparison. That howling sound went away

Yup still have the truck and still tuned. Running strong the last 50k no issues

If my memory serves me correctly tuning was around $1000 and the exhaust another $300-$400. It has a AFE turbo back exhaust with the stock exhaust flange at the base of the downpipe. Nobody has worked on this truck but myself

@@HunterSkiff nice, yeah I like the noise it makes at the end so I’d like the exact setup. Where’d you get the exhaust from?

@@HunterSkiff all I’m seeing are the dpf back ones not the turbo back

Exhaust was from XDP.com No chance you'll find one these days, EPA has cracked down on deletes and parts to defeat emissions

You think a Spade tuner and Flopro exhaust would be good? Then I would just need the EGR delete correct?

I had the truck throw a code which triggered the CEL on the first version of the tune. I emailed them and they sent me an updated tune same day which cleared the code and made the CEL go away. This was many months ago so I would assume the current tune files won't throw any codes

HunterSkiff awesome! I’m excited to give it a go sounds sweet

@@hunterschaferoutdoors0219 Thanks! keep me posted with your process!

No

delete tunes from Motor Ops. motorops.ca

Hello. The tuning was done by MotorOps. I believe theyre out of Canada. Once you have their tune installed, you can remove several of the sensors/injectors from the exhaust system. You can either cap the old sensor plugs, or remove them completely. I love their tunes. Ive been running their tune 3, which is a sport economy tune, as well as their TCM tune as well. Overall very pleased. 10/10 would recommend

@@HunterSkiff thanks for ur response did u need a transmission tune or not or not recommend thanks .

@@MrTesedgar I would highly recommend getting the transmission tuning as well. I think most companies require you to get both anyways. The shift strategy and firmness is much improved. I do believe you need the TCM tuning in order to see a noticeable increase in milage

I was gonna do motor ops, I’ve heard good things and bad things so I am just going to a diesel shop and having them do it all, tune and full delete

@@hunterschaferoutdoors0219 As far as I know MotorOps uses Duramax tuner tunes. I have no no issues with the truck with their tunes. It drives like a totally different truck. I would be very hesitant to get tunes from local tuners, especially those with little or no experience with the 2.8. Its not all about power, the Motor Ops/Duramax Tuner guys spent thousand of miles fine tuning the drivability with their tunes

EGR, DEF. and DPF. You cannot just do the EGR, it’s all or nothing

@@HunterSkiff did you take the egr completely out or just unplugged it?

@@chrisgarcia4665 Just unplugged. I have no plans of ever making the truck emissions complaint again, thus no worried about soot accumulation

Yes up 5mpg in my commute. The biggest improvement in milage comes with around town driving at just under highway speeds. My daily commute is 35 miles round trip. Most highway between 45-60mph and a stretch of a few miles that I do 75-80 mph. Prior to tuning, the truck averaged 25.2mpg, and now I teeter on 29.9-30.0mpg. On a road trip with cruise control set around 70-72mph I wouldn't be surprised if you would average 40mpg

What did everything run? I have a 17 ZR2 averaging around 20-22 stock.

I’m assuming you mean cost. The ECM and TCM tuning was $1300 and then the exhaust was another $450. The tuning is well worth the money, it’s a totally different truck with the tune

I have a 17 ZR2 stock with a S&B CAI. On the highway I get 31-34 mpg. I posted a video when the truck almost got 33 mpgs. I cant wait to tune and delete it.

Not babying anything. Doing 65mph-70mph I get excellent fuel mileage. I also use a very good fuel additive. Thanks for the reply.
