allright, i did a thread about going turbo on my pretty much stock gsr motor now i'd like to know if there are anyways to do some somewhat cheap hp gains on my motor cuz 5th gear lags too much! also my check engine light came on and i'm pretty sure i know why it came on, but my question is will the check engine light come back on if the problem still exists after i clear the code out? i would assume so, but how soon is more of the real question...
