When I was spiking 16lbs, holding 14 to redline, the FTM only saw spike 13 holding 11. Could it be that I have a bad map sensor?
On another note, I absolutly love this box! It is really easy to tune, and works like a champ. Just have to keep in mind during the install that Connector 1 is on the bottom. I forgot that and had the fun AC PCM freakout for a couple of days. Lol

I think more than likely the problem is the votage amounts that were entered in wher calibrating the sensors. Did you use the voltage amountsw that John provided in the software for the FTM or did you enter amounts bassed of some other source?
