My 04 has a bassani x pipe with 2 hi-flow cats, thinking of switching over to a mac prochamber but will i need a new tune or will it not affect my current tune?
The tune i currently have already has the CEL off, im wondering if by getting rid of those 2 cats will it throw off my current tune.No tune needed, but you'll get a CEL because of the rear O2's. You can have that turned off in the tune.
Not if the rears are turned off already.The tune i currently have already has the CEL off, im wondering if by getting rid of those 2 cats will it throw off my current tune.
