I would like the highest gains that are safe for the engine. I would not like to have the lifespan of the engine reduced by any significant amount. I do not want to have to take it to a tuner after the initial setup and install and initial tune. Basically I would like the overall reliability to remain while performance was greatly improved. Is this possible? Am I expecting too much? If I wanted 375+ rwhp, should I have bought a car that came that way from the factory? I would love to hear from GTM and Stillen about these questions. Thanks for your time and attention!
