Engine revs all over the place when cruising
Recently had the stock exhaust on my AUI 5.0L replaced with pacemakers, x-pipe, lukey muffs, twin 2 1/4" pipes, no rear resonator and two baffled stainless tips (sound fantastic from outside but despite fitting additional sound-proofing matting in boot it's still a bit loud and has a drone from inside the cabin - still trying to work that one out). Also fitted a K&N filter.
Noticable power gain however the engine won't settle on a consistent rev when cruising (cruise off or on) or on a gentle incline... the engine seems to start this rythmic rev surge. Not so bad that you can feel real a change in pace or notice the needle on the tacho move much but definately there in the audio department. It's driving me nuts!
Surely this can't be normal. I've tried resetting the computer and going through the full re-learn process but this hasn't made any difference.
I don't know whether this is a transmission issue or is because of the new exhaust or maybe something else.
Should I be putting a rear resonator (twin chamber) back on?
