Hello, i own a 96 facelift version japanese wrx wagon with an auto box, I've put on a K&N air filter, full magnex stainless exhaust without middle cat, and a cobra 100cell flow cat downpipe, im wondering what the boost should be and also how much power the auto box will take before it decides to terminate,from what i've read on the net its around the 240bhp mark as standard any help would be much appreciated, thanks rick1702
