I'm new to this forum and totally new to wrx's. I bought a 2003 WRX 2 days ago that has been modded fairly well. From what the guy told me, he bought all the parts (aftermarket tmic, fuel injectors, short ram intake, full turbo-back exhaust system, and entire suspension setup) and had a shop in San Jose, CA tune the car to work perfectly with them all.
Only problem is.. he told me the boost is set to limit at 21psi, which I've heard is incredibly too high and unsafe for a mostly-stock WRX. So my question is this: how do I lower the limit back down to say, 15-16psi? Would I have to have the ecu re-tuned? Is there an easy way to manually adjust the waste gate? I'm very worried about screwing up this car that I've only owned 2 days. Thanks in advance! Nice site you got here, btw!
