With the freezing temps here last week, the Jeep was running faster than ever. However, when going hard WOT would throw code P0108 dealing with the MAP sensor. I have a 2 bar and am running around 12psi. After making some inquiries was told the cold weather was pushing the 12psi upwards of 15psi, or more, and the 2 bar can't handle that extra boost.
My solution was to turn the boost control knob on a lower setting and by ordering a Omni-Power GM style 3 bar map sensor. Also, will have to get a re-tune to recognize the new map sensor.
