RE: HHP CMR Tune
JJMPB,
At best 2-3 hp increase if you already have the 93 OCT CAI Tune. I spoke with them today and the 93 OCT CAI tune has fuel and air to their limits already. This tune helps you apply what you have to the rear wheels via shifting improvement/firmness and throttle response. A real seat of the pants improvement and probably a tenths to two tenths quicker in the quarter. If you compare this tune to original stock, then you probably gain 40-45 hp with CAI & 180 degree thermostat. That is my guess from Dyno's I've seen posted in various forums. There is one side effect though, it really isn't one that I would worry about or use anyway. Besides you can always go back to 93 OCT CAI Tune or Factory Tune.
