i have an r33 non turbo and i want more performance there are so many things that have been done to it but i still find it hard to get from 0-100 in less than 9seconds i crack 8seconds wen im lucky. i shift every gear at about 6 and a half grand so i dont think its running the way it should. because it has CAI,pod,high flow exhaust 3" all the way extracter as well. so i dont understand why im not getting what i what.
this is all i want 0-100kmh in 7 seconds thats it, thats all.... What do i need to do because that one second is letting me down..... will a tune do the job? an LSD? please help... i dont want to blow the engine up or have any illegal things.. and i dont want to spend to much... unless its werth it
