Ever since I missed the Scoobynet group buy earlier in the year, I've been meaning to get one of these for my Impreza, a MY95 WRX (with intake and exhaust mods).
It would be really helpful if any of you guys who bought one could post what your experiences have been, like did you get the power gains you were expecting, was fuel economy and driveability improved....? I'm also wondering if by having the Z4 ECU in my car as standard, the benefits will be less noticeable than on an earlier ECU?
Cheers!
