i have a 00 5.0 awd eddie baurer with a mac intake and a superchips programmer, i need to get more power out of it. It is going to the shop tomorrow for a custom cat back with a magnaflow muffler. But i want t know what the nextstep should be to get to around 300-350 horse at the wheels. I just need to beat my buddies 02 325ci, he thinks its the gratest car in the world. i almost have him now, but he just got exhaust and a true cold air intake.
