Can we assume you have a scanmaster?...if not, its a must. I like a wideband too....its a great piece of mind when you start pushing it. Alky inj. is a great add....allows you too take boost well over 20Lbs.....a good converter will be a good add too as you may be leaving alot on the table in slippage ..its just a matter of time till you have need for one. I have mine at 26psi with zero knock...makes it a whole new driving experience!
