What do you guys think. Car has ported throttle body, Spectre CAI, Pypes LTH, And Rick's Low lift Little Lunati. Unbalanced exhaust, cat/mid muff delete, stock mid pipe, solo axleback.

Not bad but it is not about numbers but track times. Mine was a bit less HP but from the seat of my pants i could fell a pretty big difference. The torque was almost exactly the same as mine.

It ran a best of 12.89 at 112MPH 2.09 60ft. Felt like it wasnt launching hard at all. No wheels spin off the line even with no track prep.Originally Posted by norton13
I have a similar cam spec'd by Pat G (218/224 .600/.600 113+2) and my numbers are 407/395. So I'd say your numbers are just fine. You have a little more HP than me but I don't have a ported throttle body.

Yeah it should obliterate the tires, you're probably choking it with that exhaust. Also, the ls3 valves and head milling makes a big difference and does not look like you have that.
Went to the track last weekend with slicks and had the same result. Fastest was 12.96 Felt like it was falling on its face off the line again. Is the dyno chart supose to spike like that at low rpm? Or is it suppose to be smooth the whole way up? I have a feeling its. the tune. It smells rich at idle wich also makes me think its the tune.
Sounds like the tune. Both ECM and TCM.

PatG did the tune on the dyno. They couldnt get my O2 sensor out to pipe read the A/F ratio so they just clipped it to the back of my exhaust pipe. Dont know if that might have affected something. I dumped so much money into this thing to do it rite, Im really starting to get frustrated.
My thought would be to go to pat, tell him what it's doing, and see what he thinks....

Anyone who has ever worked on a car has been in your position, and sitting cross-legged on a concrete floor with a dim shop light is its own kind of hell... Chalk it up as one of the rites of passage.

That affects it, yes. Any air leaks between your exhaust port and the tailpipe will throw it off. I usually see a .5 difference.
