Final numbers came out to be 229.5 rwhp, 249.9 rwtq. This was @ 7psi, btw. Thats a jump of 40 rwhp and 25 rwtq over the original tune in the chip when I was running so rich, so for now I am pretty pleased. Jim D. said since it was detonation free we could add a couple more degrees of timing and see a bit more hp, but I need to go back next week and get a little problem tweeked out. Its obvious on the graph that at 5K something is cutting the power. Jim said that after talking to someone @ SCT that it appears to be some kind of secondary rev limiter or something that needs to be worked out. As it stands, it looks like it wants to pull a little more to maybe ~240 or so if we can get that fixed.

Other than that, I think I am pretty much in the ballpark of what this setup should do. I do think the trq curve looks pretty nice for a cent blower. Oh, and the red numbers are just for comparison sake when I had just the pulley, cai and duals.

What do you guys think? Does it look like its where it should be (aside from the dip @ 5K)?

Looks good for sure! That's way more in line with what a 7psi split port should do. Those numbers would give a GT a decent run. :nice:

Still looks a bit on the rich side to me though. You're dipping under 11.5:1 through most of the high RPM band. I understand that maybe your tuner wants to keep it on the safe side, but 12:1 or 12.5:1 is still sufficiently safe and would net you some more power. (look at where your untuned, stock fuel curve was with just the bolt ons .. it's safe there)

Does look like there's a bit more if it'd keep pulling to 5400, too. Good numbers! I still say you should see 240hp/260tq. :D
 
Yeah, we aren't done yet ut we were there for hours yesterday and it was getting sooo hot that it was taking the car too long to cool down so when Jim can figure out whats up with that 5K rpm dip, I'll go back and get that worked out and see about getting the a/f tweeked a tad more.
