It probably is Shawn. I mean, it has .24 bigger lift on the intake than I do and the same exhaust lift with a hair less duration.

I had IPS tune my car as they have one of the best tuners. I found out that he was sick and he didn't tune my car.

I'm taking it to my old tuner who has tuned on all my cars. We will see if he can work his magic.

Tuning WOT on a NA car is easy. Fuel air and spark

well had the IPS tune checked.....not so good.

A/F was 11.7 and the timing was 21. Made 448 and 404 on the Dynojet.


New A/F is 12.7 and 27 degrees of timing. made 468 and 420. numbers are SAE.

It was 88 degrees with 65% humidity.


I'm happy considering I don't have a UD pulley or ported intake.

That's a ton of timing. Did they try lowering it to see if it picked up power? LS3s don't need much timing to make power

I'm sure they know what they're doing so I'm sure it's fine.

Did you notice a driving difference in the 2 different tunes?

Good stuff. I don't think it's apples to apples persay, but for comparison, mine is 21* in the midband and 24* peak
517whp/462wtq


When you taking it to the track?
