Hi !

Have you look on these two different graphs ?

and

It seems that the air/fuel ratios are near the same ! What are your comments about it ???

Why on the Revitup web site they claim a 45whp gain from the PSI-FI kit, where dyno shows about 25whp and 30 ft torque ? These are nice gains nervertheless...

Personnaly, I bought a 3" pulley from Pulley Technologies, and will install it friday ...

Thanks, have a nice day !

Hey good deal that is MY DYNO graph. I faxed it to Pulley Technologies on Friday I guess they updated there ebay add. Good deal now I do not have to post it up. :D

If I took the smoothing off the dyno it made 242RWHP.
