Do i need a retune?
My tune was wrote w/ a CAI and a SI-SO 40 series flowmaster. I just bought 2 hi flow cats, X pipe and 2 super 44 flowmasters. I believe I read somewhere when the cats are swapped out a tune is a good idea. Any insight? hoping to have everything installed this week!

This is just a guess, but I think you probably do. However, I think the changes are fairly minor and I doubt you need to wait on installing those mods. Bill, of course, will give you the REAL answer.

Given the extent of the exhaust mods, I do think we should readdress the fuel curves a little as you are probably running a touch lean. Any single mod would probably have been fine, but compound mods are pushing the limits.
Take care.
