I would like to get my audi to 350hp but I dont want to spend the 7grand for the stage III kit. I was wondering if I did it myself if I can reach 350-400 hp without spending that much money? I would like my tt to run about 12.0 in the quarter and be even better for autocross but I dont want to run too much hp and be running hot the whole autocross. Any info would be great. I have a 02 225.
