Just a random question for you guys.... I currently am running 2.25 cold/ 2 inch hot side intercooler piping.... i ordered the 2.5 inch all around kit from Greg and i was wondering how much would this affect my tune? I am getting it re-tuned next fri, but I am just curious if by installing this after, would it throw my tune off at all? Or should I just install it asap just to be safe? Thanks!
