just wanted to see if there is any negative feedback on tuning. I am still waiting out my warranty to tune

No regrets here. I have heard of some people who regretted it, but it was based on who they went with as their source of tuning the truck.

Some tuners make things a little too hot for our engine (or transmission and driveline parts even) to handle and things don't hold together. I can't say I've had any such problems with hACKmans Customs (Jason Hackler) who's tunes are sold by Shield & Spear Performance https://www.snsperformance.store/

Jason's tunes may not be the biggest out there as he has said before, but they are focused on being reliable, safe on your truck, good MPG's and also giving your truck better performance (it won't be a Corvette, or even like a tuned and deleted 6.6 Duramax, but it's a world of difference from a stock truck).

I opted to tune at 45k miles and say the heck with the warranty because I didn't want to deal with DEF anymore or worry about the DPF acting up. That and the EGR isn't putting nasty crap back into the engine anymore.

No regrets tuning mine. I run the GDE off road tune and love it.

I have a 2018 CCLB and I put the GDE tune (ECM & TCM) in it with about a 1000 miles on it. I could not stand the crappy pedal response. The truck runs great and shifts great!!!

I GDE tunes mine at 58,000 km (40,000 miles).
Could not be happier.
Throttle tip in no longer has any turbo lag.
Passing power improved.
Not sure mileage yet.
Trans tune Is definitely worth the $.
Green Diesel guy exceptional bunch to work with.
I had some self imposed issues and they were extremely patient and dedicated to resolving my issue.
Big fan!

Hi guys, first post here. I’ve been doing homework due to a future delete and leanin toward the GDE. Just curious what exhaust y’all used and if you did an EGR delete as well.

I have GDE engine and trans tune.
Stock exhaust which maintains nice quiet exhaust note. DPF still functional so no rolling coal. DEF shut off.
Mileage improved, towing improved, throttle response improved.

I didn't actually remove the EGR itself. Just put in the tune in a little under 1K on the odometer and it's only got about 3K on it now. I will say you have to make the choice and roll the dice on the warranty, but if I had to do it all again I wouldn't hesitate for a second. The only other things I have done is the POPinLock for the tailgate ,a LEER cap and a Titan fuel tank.

I have the offroad tune. For exhaust I just cut out the dpf and welded a piece of 3 inch pipe in it's place. No louder than stock.

I went with Duramax Tuner, no delete yet! Great throttle response and has 4 settings. Extra power when towing and better MPG's. With my 6" lift I was able to get 31 mpg's again, as well as fixing my speedo correction too. Included trans tune as well to make it all work together.

Mine was already tuned and it rips. Really can't see any downside right now. Still has all the EPA nanny bits too.
