To make a long story short, I've got a built setup capable of revving well over 7K (ideally looking for 7500). I have done all the obvious raising of limits but regardless of what I do I hit a wall at 7K and the car hits some sort of rev limiter. Yes.......mph params are set correctly.
My question is this: does anyone know of a hard coded limit with the 99 C5 pcm (0411) that will not allow automatic shifts over 7000? I'm past frustrated and I'm on the verge of installing a stand alone setup at this point.
Thanks for any advice,
