Are you Ms2? Smoothing/lag enabled? Where you pulling the 5 volts from? Grounding? Also, like Dino said, use MAPdot or increase the threshold for change.

MS2, no changes to the smoothing/lag area, TPS Vref powering the TPS, Crank and speedo sensors as I was told to do by other MS users. Grounded on the firewall with all my other sensor grounds. Right now I think my AE settings are 100% TPS based. Just checked the smoothing factors and they are all 50%, default settings.

Just got in my car and hooked up my laptop and it got worse. Calibrated while not running, started it up and moved to -2% (figured because of the vacuum). Calibrated again, goes to 4% while on the throttle stop. Time for a new TPS? I could take on off my Avenger to try it out...
