Nurrish i still cant believe you've done this?? Why not just drop the power down and keep the car SC'ed??
I know the feeling you guys are going through. When i picked my car up from abbey i drove 2 hours before i even put the radio just listening and watching all my gauges!!!!
Cars are just machines, If you look after them and build them right then they work right. You may have some extra problems over an NA car but just deal with them! Any one who drives a car that is tuned will have small doubts in there mind but the feeling of power/performance gained should bring a bigger smile than the "sh*t what was that small nosie that only you heard and the passenger did not hear?" lol.. The smallest noise im like "sh*t was that the ???? letting go" Just put your mind at rest and drive the car how it was ment to be driving and then worrie later! lol..
Tell me this is not the end for power tuning for you?? Ill say it once more GO BUILT TT OR V8 OR GTFO!!! LOL>.
