I finally got around to installing my PHP chip and all I have to say is WOW! This truck feels totally different now, in a good way. The touchy, sensitive pedal when driving over bumps and dips is gone, and the shifts are smooth and crisp.
The only thing is that the smoke show setting doesn't make any smoke. The 100 Race makes more smoke than the S.S.
The setting I went with are:
Stock, 80DD, 100 Race, Whisper Mode, 80HP Light Tow, Smoke Show
Well done PHP, another satisfied customer
