I just installed the C&L racer intake and custom tunes from Brenspeed through the SCT programmer. I am in total shock. I thought the 3.73s were a big disappointment but it turns out it was the computer. All of the guys with automatics rave about shift points being better but I had no idea how much the tune would change the acceleration with the manual. Now I can finally punch it and get snapped back into the seat. So long tires, its time to have some FUN!
