I have this EBC and have been running it with some success, but can't seem to dial it in perfectly. It seems to be twitchy when on WOT and I have thoroghly read (and tried to understand) the settings recommended by the manual. I wish you could dial in the PSI instead of the duty%!
Anyway, I am running a JDM STi version 7 motor with a stock ECU, VF34, 565cc injectors, and 3" catless exhaust. I also am running alky injection. I want to run 21-23 psi smoothly. Please help me dial this sukkah in!
