Mr head I do read and I get different opinions on this subject, I also see different results on two different sc's with my own eyes. I am new to the threads and I will read however I thought I would try to figure this out by posting the threads are they her for that purpose, right? No I am not in nascar engineer but I do know somethings, I know I have a fast well tuned 1992 sc400, I have done the intake, exhaust (except headers) ecu, d.t.c, Nos, suspension, electrical, etc... If I new how to post a picture of my 100% restored show lexus sc400, I would for all you non-believers. Do you own a car? or are you just reading and learning and not driving?
