retune required?
New to the chip world, ordered last week and it's currently traveling cross country. can't wait. going about things a little backwards though, and wondering if i screwed myself. I ordered my pheonix based on my current exhaust setup (stock, with muffler delete). since ordering, i decided to go ahead with mbrp 4" turbo back with no cat or muffler. its also in the mail. is this change signifigant enough to worry about?
Also, i didn't mention on the form that i have the 6637 intake, although come to think of it i dont recall any questions on the order form about intake.
Anyone have any input?
