yeah, what mike and scotty said. Just get it done and ull see. GAWD!!
I got the same stuff done to my car. U can run up to 10psi of boost with ur stock map sensor IF and only IF u have a chipped ecu. If u try to boost ur car on a stock ecu as soon as ur ecu sees boost its gonna freak out and start popping and ur power will hit ricok bottom. U can try it if u want but u risk ruining ur map sensor.
