: first off, I want to thank Gyro for doing a beautiful job on them...almost too pretty to put on the car LOL. If any of you are contemplating turbo upgrades the quality and prices DSP is offering are simply outstanding. Hopefully will have my car back together by late next week..I cant wait to race my bozo neighbor ( first one to 100mph )w/the C5 for $500...I gotta try and do a "double or nothing" second race w/him for more mod money...I think that money is going to go to the 740cc injector/direct port NOS fund :-)
