your four power gainers are only headers, exhaust, manifold and intake right? thats a pretty good power increase

The large gain are from nitrous too but the base are the bolt ons... Come on there has to be some other big number dyne sheets out there

Nice thread. You guys should also post up what mods you have to make that power. That way it will help others and give them an idea what mods to get. Wish I had an IS-F haha.

Anyone running different ECU, or is all this power done with stock ECU, how are the AFRs??

:egads: The IS-F ECU has not been cracked, nor will it most likely ever be.

So your telling me you can add 100-150whp without changing MAFs, ECUs, etc? Thats like the holy grail!!!!

You'll only see gains like that with juice (nitrous) or forced induction (turbo/supercharger), you won't get that with just regular bolt-ons.And part of the reason there aren't any reliable turbo or supercharger kits for the ISF is because the ECU cant be tuned properly.
