I bought the Lethal off road x pipe, it will be here thursday. My question is can I make whatever changes need to be made in the tune myself with my SCT tuner? Or do I have to have Evolution who did the original tune send me a new file? I know I need to shut off the rear o2's. But isnt there also a feature where the computer dumps fuel to cool the cats or something that also needs to be turned off?
Thanks!
Thanks!
