I am having great luck with the quadzilla, shifting and all. Will see what the mpgs do coming up tuesday as I roll to FL with it

PPE:ro) :ro) :ro) :ro)

Some will say Predator and others will say PPE.. I think you will have to use them and then decide.. You might consider the new Bullydog Tuner that is out. You can try it before you buy it.. Some have had good results with it.. Good luck

I've had quite a few different one's. If I did'nt have the TTS Extreme (which I would'nt give up) I would take PPE as my second choice.
