got the software loaded into my computer. plans are to link up via the internet with mast motorsports...who built the engine and programmed the ecu..and let one of their tuners look at the engine parameters under running conditions and make necessary adjustments. should only be minor to smooth out low rpm operation. i most likely will have them to reset the sensitivity. i have never done it this way but i trust them for this. got the ''''heater and defrosters ''''working this past week. maybe a bit hokey for some but works well, adds hardly any weight, blows lots of heated air, and is very simple. i even used one of the Ford dash vent regulators to direct air under the dash on the passenger side. the 3 inch bilge blower moves lots of air when turned on.
