Are the Greddy kits on the RSX-S decent fast? I noticed they have the same smaller turbo, no intercooler, etc.. Now they come with a preprogrammed E-01. Overall it looks like a nice bolt on kit. In reality how is it, anyone have dynos or experience with it?

 

Put one on a car this summer. Dyno'd @ 210 whp with whatever the wastegate boost was set at with no intercooler, and that was with the e-manage throwing an error code for bank 1 running too rich.

Never re-dyno'd it after we did a custom FMIC setup and had the e-manage reflashed by Greddy.
