can u guys tell me were i need to tweek on these tunes thanks


the first two a hard hits and the third was first start in the morning then drive to work and yes i know i got to get an intercooler lol dang iat's

 

I would start with your PE enable parameters. You are well into making boost and are still in closed loop with the fuel trims updating to where they are adding 50% fuel and your narrow band O2s are less than 30 mv. Quit using the default scanner config and add some meaningful pids. And I usually don't even reply to posts like these with absolutely no details on the vehicle but the logs are so bad you are well on your way to breaking parts.

 

I THANK u for any help yr willing to give and i do apologize its a 2005 gmc sierra truck 4.8 all stock with 70 mm turbo no intercooler yet

 

do you have a wideband?

 

Its on order

 

You really need a wideband... and a 2 bar tune would help us so we can see how much boost you are actually making.
