ok well it wasnt a personal attack, you need to re-read it once again i guess. anyways,there are good and bad things about dyno tuning cause meaning the bad things is that if you havent gotten a base line dyno with no mods you cant go off anything to see what all gains you have gotten. and if you dont have your stock parts then you wont be able to get a accurate base line. the more mods you have the better the sct works, yes it will work amazing on a stock csvt but say you have headers,a turbo,ect... it will work better. plus you dont always have to dyno tune a car. a street tune is perfectly fine just datalog the car and get the a/f good and the rest is cake from what i understand.
