Fellas, im getting ready to sell everything. HELP
Im stumped and cannot figure it out. I have a 6.0 forged and studded, 317's, custom brian tooley turbo cam, S475 on 15 psi, dual water / meth spraying 21 GPH total of 50 / 50, my air temps are in the 130's with no intercooler, blah,blah...On the dyno, its 11.5 across the board, 18 degrees of timing and only makes 430 rwhp! WTF?! My tranny is a stock TH350 with a cheapo Summit 2300 stall. The dyno graph climbs up pretty agressivly until 4k then starts to level out slowly. Am I blowing through the converter? Are the clutch discs in the tranny not holding up? This combo should be making another 200 HP
Suggestions?

It could be a number of things........what do you have for valve springs? A cheapo Summit stall for sure is not helping. Where are you reading boost at? Personally I am not a fan of meth. I have seen guys try to use it and lose power

I agree with Thadd. Meth helps sometimes and then not others. My car losses power with meth(over 100 rwhp at the same AFR, low 11's)
If you can't take advantage of TONS of timing or boost the meth is useless.
At 18* you are not close to problems with 15 lbs. Pull the meth fuse, and start back on the tune, adding fuel as you go. Your car will be lean if you do a full pull, so start of low and retune the whole car.

Oh wow. OK. That high of IAT would make a difference.
My IAT off meth @20 lbs are around 175 after a 1/4 mile run and 130 with meth, but it still makes more power off of it.
