06 RPM surging
So the only things I put on this truck is k&n, and true magnaflows. Now the thing is surging at any rpm cruising or not. They will jump up a couple hundred rpms and I'll hear a bumping sound in the engine compartment. I thought the intake was loose but it's not. I got an SCT "can" tuner and it made it happen more frequent....... any takers?
