How are you calculating that... lol 330-340??? You add 10%-12% which puts you right at 310. Not arguing with the number just your calculation.

I am hoping to dyno my car some time next week or two - time permitting. Then I will throw on the stage 1 (If I can ever get it back from my deadbeat friend bigdeep) Then I will post some numbers.

BigD - I believe the answer to your question is going to be software. I tried searching for you, but everything just says "fine tuning" This to me indicates that perhaps it was nothing mechanical.
