I think the best way to raise the redline is to get an aftermarket CPU or piggyback chip that will delete the fuel/spark cutoff, and then you will need stronger valve springs to prevent valve float. Or just get the Cobb heads with the valves, springs, and cam, then you should be pushing some power! By the way, I don't know which chip will do that for you, but I'm sure someone does!quicksilver said:Yeah, a SC would be sooo nice!!! I need to start saving 'cause I'm outrunning my warranty!!!
Speaking of redlines, how do you go about increasing them?? An extra few hundred rpm would be really helpful. I'm guessing there's no "magic screw" to turn!
Oh, NA rules b/c turbo lag sucks!
i think it's due partly becuase the power band on a RS drops severely after 5500 rpms. once turboed though, it can pull all the way to 7k no problem.Dave G said:Has anyone considered ram air for the '00 2.5RS? Is the tach limit at 6200 to limit max speed or prevent valve float?
