One quick tip,,, many times you cannot hear detonation even with a quite exhaust system.
That is why I recommnd the J&S safegaurd system,just my two cents,& strongly recommended esp w/cast pistons.
Second tip would be to install an alky injection of some sort. I am sure w/4 lbs of boost you can feel it but boost is very addictive, your going to want more.
Unless you have very good self control & keep the boost down,I would strongly suggest those two ideas.
