Over the course of the next several months, I am planning on doing some modifications to my 98 GTS. I plan on installing a Corsa exhaust with high flow cats, a good set of headers, possibly Borla, ported and polished heads with larger valves, and 1.7 roller rockers. I am located in West Virginia and believe it or not we don't have a lot of aftermarket Viper tuners like Jason Heffner or Doug Levin close by and I don't want to pay to ship my car far away to get these things installed. I have a friend at work that is very knowledgeable about cars and has built several motors. We feel that together we can install these modifications. Assuming we install everything properly, won't we need to recalibrate the computer for maximum horsepower gains? How can we do this? Is there a standard upgrade module I can buy such as the VEC1 or does this have to be done with multiple runs on a dyno?
