So, I take it you have an EVO? Look up JESTR tuning and give him a call. He can give you a street tune and reflash your ECU for about $250. It will be the best money you will ever spend. Take the SAFC2 out and sell it.

John had his car tuned by JESTR and I will be the first to say that the tune was a night/day difference. I drove the car several times before the tune and once after and let me say I was freakin impressed. The car has better throttle response, turbo spooled up much faster, and the car pulled all the way to 7500 on the stock turbo. A bigger plus is the car gets better gas mileage when you arent busy laying your foot into the throttle. All in all, JESTR tuning is the way to go.
