I have a US version 2017 colorado 2.8 turbo diesel with the auto trans and would like to tune it a bit. I have tuned turbo LS stuff but never anything diesel and this also being my daily driver I dont want to mess it up. I have used the search tool and doesnt seem to pull anything up but the same two threads.
Just like everyone else i want to get more power and MPG out of this little duramax because it seems like it has plenty of room for improvement.
So far I removed some of the torque management stuff and lowered the MPH needed for upshift in all gears except 1>2. Turned up the shift pressure by 10 percent. I am going to mess with TCC lockup a bit so it locks up earlier and in other gears.
Now engine tuning is where I am lost here. What maps do I change and what in them do I change to make more power and MPG when cruising. I have shut off the EGR for reliability purpose.
Thanks ahead of time.
