I'd love to see what a stock 370z does on that dyno.

I dynoed my car there bone stock, made like 250something.

I dynoed my car there with full bolt ons and made 290something.

I dynoed my car there with the supercharger and made 380something.

I then took my car to a local dynojet and made 432hp SAE (455hp STD, STD is what both Stillen and GTM use when they publish dyno numbers)

....as stated...stock cars make 240-250whp on this dyno...340 is a 90-100whp gain over stock....and on par for the setup IMHO.

...the tip-in knock as discussed has been observed even on stock untuned cars ....in this case it seemed to be a bit exaggerated....I theorize there are a few modes that the ECU reverts to in the event that overheating occurs..and with the combination of the SC kit/florida heat/extended idle/slow cruise/ A/C ...etc its not impossible for these already tempurature sensitive cars to reach the threshold.....without access to these possible alternate schedules its difficult to assume they are at a set point/value...I have seen this behavior exibited using both Osiris and Cobb to tune with and can only hypothesize on the culprit. One thing I CAN say is this is not the first kit I have seen and am still pleased by the results I am achieving with the Stillen kit using UPREV software. I have no complaints thus far and will happily continue tuning these kits as they come.
