I believe it to be alright. A good source for info like that is enginuity.org forums. I think that they refer to it as a stage 2.5 upgrade and you will need a retune. The car will build boost beyond what you have it set to now only because of cooler and denser air coming in. Also winter is right around the corner so you may see a 1 to 2 pound boost fluctuation. Good if your car is ready for it.....bad if it isn't.
