I was looking around and have been troubleshooting my car, since I am not getting full boost. I have checked the vacuum lines and for boost leaks. But have reset my JB4 (ISO) to defualt settings, but what exactly does that do? When I reset it my map that was previously selected is still in the same position...settings like auto DCT off and guage sweep are still turned on. Shouldn't these all be turned back to the defualt settings???
