Well, I got a baseline dyno on the Firehawk yesterday, and while I'm not terribly dissapointed, I'm also not super happy. The car made 282RWHP and 305TQ. While these aren't super numbers, and kind of low for a stock LT4, the culprit is very apparent. The A/F was running at 11 for almost the whole run and dropping to 10 and below over 5000rpm. This is WAY and I would guess that once I get it tuned properly, that it should pick up probably another 20HP just from leaning it out. So the big question is, who should I go to for tuning?? I was thinking of PCMforless.com, but I've also seen several posts on here about madwolf and it seems people are really happy with him as well. Either way, I'll be going back to the dyno after the initial tune so it can be fine tuned.

Evan,
I can definetely assure you there's another 20-25 RWHP to be gained from tuning. Member INTMD8 has an LT4 SS and he dynoed at 311 RWHP after tuning it.

You might talk to INTMD8, he has a 97 LT4 SS, and I remember I think he dynoed about 290rwhp stock, and after just tuning the car (air/fuel, ign, etc) he got 311rwhp, 325rwtq. You can usually find him in the forced induction section.

FWIW, shoot for around 13:1 on your air/fuel, that should help alot
