those are the actual numbers and its part ignition breakup part running waaay too rich. honestly only had my car on the dyno three times and i was scared to tune it for fear of doing something wrong. i learned alot tuning on the street. its not the prettiest graph but it did it

Just keep in mind that dyno's can be told to lie. Instead of looking at everyone's dyno charts just hit the track and see what mph you get. To me that is more meaningfull than a dyno.

best et was 12.0 @ 118 mph blowing the trans and twisting the input shaft with my decent driving but nothing amazing and only a 1.70 60 FT... i learned alot from this car

Thats why there are to many variables to figuring it based on trap speed. Driver could suck (Vosko)
, bad launch, traction problem, tires etc can all effect trap speed. Those wont change HP numbers.

what kind of wheels to you have on the car? My car showed a 20-30 rwhp decrease when going from the stock 16x8's to the massive 19x10 (285 tire) rears- with no other change in the settup of the car, if anything it shoudl've shown higher numbers because it was a little cooler outside when i dyno'd with the 19's. Having to rotate all that weight apparently took some serious power.
BTW: I made 404 rwhp at about 16psi with the 19's and A/F numbers around 12 (not exactly conservative) with a mild streetport

My Dyno Pull...
This was at 16 psi. Don't ask why they graphed it in MPG instead of RPMs...

Very Nice Piano!
I see your a/f is a bit leaner. Scott did'nt build my motor so he did'nt know what was done internally......so he kept it rich, at least that's what he told me.
