I haven't really seen a performance gain by my comp upgrade due to I'm still boosting the same. I'm sure its making a few more ponies from the cooler air charge, but it's real performance will come out when I break out of the 20-22psi. The new motor will be 25-26psi after the intercooler.
this is what i'd like an explanation for, seeing as how he just informed us that he is running a stock turbo with nothing more than an upgraded exhaust housing... you haven't seen a performance gain by your comp upgrade because you haven't made that upgrade.
you make a claim like "i'm still boosting the same" with an upgrade you dont have and some people will believe you. they'll do the same thing and get 28lbs of boost and blow a head gasket or crack a head because you lied. not cool at all.
