Is the truck itself stock?Originally Posted by Rogernles
yes it is stock all but msd coils and cold air intake and 3 in exhaust and no cats
Got any check engine codes?
What about a datalog?
i do have a log and the only check engine code is for rear o2 and evp pump
Roger, if this truck is stock why did you apply the 2 BAR OS to this computer?
Do not use the 2 BAR OS if you never plan to run boost. The tune now has 2 BAR map sensor data in it and the VE table is now completely wrong because the table is now double in size but running a 1 BAR VE table in it. You can't run a truck with 1 bar MAP on 2 bar MAP sensor settings.
Go back to the stock file with a write entire and start over.
Once you do that you can alter the PE settings some. Change the hot/cold pedal enbable to 65%. Lower the enable torque to 50%, lower the rpm delay to 1,500rpm and set the time delay to zero seconds.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
