Map sensor

truck seem to get quiet during acceleration 1200-1800 RPM otherwise runs normal I didn't get a error code till I disconnected Quadzilla M3. Then I produced code 0237 (map sensor voltage too low) cleared code and left Quadzilla disconnected , seems to run normally. any ideas as to my problem I've been waiting a while before reconnecting Chip

When you unhooked your box it opened the MAP circiut because the box ties in to the circuit.

Why did disconnecting the box also make the truck run correctly under acceleration, do I have box problems? or is the box magnifying another problem?

Check for any little corrosion in your MAP Sensor plugs. Check for bad wiring, and check the plug connectors on each end and make sure they are getting full contact once plugged in. I had MAP Sensor Voltage Too Low back in the spring, ended up being a little bit of blue (corrosion) on one of the contacts on my XZT+ Plug. Once I plugged the stock MAP Sensor back into the Map Sensor itself, there was no corrosion there to cause resistance problems, truck ran normal.
