I am using an 18ohm board..the car knocks on map 7, I cant use it at all, but I still have bog on the lower maps as well. Car seems to run perfect other than the 3--->4 shift. Dont have a BT, trying to find a local shop that can help..

Are you running a normal JB3 or a modified board? The modified boards are a lot more sensitive to things being perfect as one would expect when pushing the limits.
