Hello everyone,
New to the forum and new to the gas job tunes as well. Just traded in my duramax for this 2011 sierra denali 6.2L. So far i love it but after the test drive i could tell it needed a tune bad. So as i love learning new stuff here i am!
Just looking for tips, tricks, and data you guys may have.
Here is what ive changed so far. In addition to this id like to tune in my high octane spark table since this truck is pretty rich out of the box. Looking at adding 2 degrees and adjusting as i find KR.
