Hey guys:

My much anticipated dyno numbers are here. I went to the tuner today and here is what I got.

462.79 rwhp

428.62 torque

Does the torque seem a bit low???

Also, the dyno used was a dynojet. A/F was 11.5 We kept it conservative. Originally, the plugs (ngk iridium IX) were gapped at .038 which is where Steiggy reccomended. We noticed some spark blow out at 6k rpm and closed the gap to .030 This seemed to rectify the problem. We gained another 8 hp by doing this. We also bumped the timing up 2 deg. Max boost psi was 15.5 between 2500rpm and 4500 rpm.

We used a diablo tune and also needed to install a mafia.

I honestly was expecting about 480 hp and about 500 torque. The tuner said if we went further with the A/F ratio to 12 or even 12.2 we might see 475.

Nonetheless, opinions are wanted on this. I do have graphs for rpm, boost, maf voltage and fuel pressure if you want me to post them.

Thanks guys.
