Dynoed 407 with 3 psi on TTi kit Well I finally got to the dyno and I wanted to see how the car was running before I added any more boost. So with 3 psi I managed 407 rwhp. I was a bit disappointed as I have H/C (10.8 CR) as well. The A/F ratio was around 12 is that ok? I have the PE set at .81 so I'm figuring I'll drop that to .78 and turn the boost up to 6 psi, will that work?

i think thats what hes saying---- that a/f ratio is a bit lean for my tastes as well as what many people do- 11.3 to 11.5 is a safe a/f ratio- if its an N/A cam, and your still on the C/H tune then im sure there is plenty left in the set-up

lol I just got the 3psi spring, I think its a bit above that, something like 3.5 psi really. Can is a Cartek cam, came with my Stage 2 h/c cam setup, I think it was called the "H" profile when I got it. I didn't know anything about cams back then so I just told them to send me what would give me streetable power. I should also state that I only dynoed 350 rwhp without the turbo ( but using headers) which is really low for a S2 H/C package. Anyway, I'm hoping to turn it up to 6 or 7 psi without blowing.
