New to HP Tuners and Gen V GM engines, but not to tuning forced induction engines, I initially decided to hire a tuner instead to taking the time to learn the platform and tool. The tune resulted in dyno numbers that looked "OK" (619 TQ / 574 HP), but the car feels very lazy and is down 5 MPH in the 1/8th mile from bone stock.
SO, I decided to purchase HP tuners and look at it as a learning opportunity.... Wow, are these systems complex! Thank goodness for the Compare function as I was able to compare the stock tune to modified tunes as part of the learning process. What i found in the tune i paid for was he tried to maximize boost, but to do so pulled almost 10 degrees of timing, which I believe is what I'm feeling in the car.
Of course I'm still very nervous and would really appreciate a quick review by someone who's knowledgeable with these cars.
The new tune is attached and I truly appreciate your time and assistance.
BTW - the car has a ported blower snout, 95mm LT5 TB, and Roto-Fab CAI.
Thanks in advance!!
