hey guys, i just had my car tuned at race-prep yesterday and just wanted to leave some feedback on them... first of all they are really cool guys, they care a lot about what they are doing to your car and look for your best interest. the time goes by fast too as they talk and just hang out with your while they are tuning, with the mods in my sig they tuned 348 hp, and 361 tq with nice curves. thanks a lot guys

your a/f between 2500 and 4k needs to be adjusted a bit more... you can get a little leaner. you may see a bit of gain down low
