O/R X isn't near as bad as catback X imo.
Wendell, ask Kyle about his friends silver cammed w/ O/R x. Its Daniel's car I believe (a friend of his) But it doesn't sound half bad. Hell of all people he said if Idle isn't enough out of the pro for me to just go back to an X lol
But Im all about the pro as well.
But OP nitrous can put some stress on plugs, Ive heard those auto lites aren't good for long w/ nitrous. You probably just used them up or something.
But you should join www.moddedmustangs.com
, I post most of my tech there, and im usually around there everyday, where as here I only check in occasionaly. and Im looking into nitrous next, would love to get some info from you.
