At this point I have given up, JB4 is ok but its not earth shattering power even with map 7 and 103 octane... Proceed was and felt much more powerful but it was also very unstable and car was constantly in limp mode. I am hearing really bad things about OBDII devices that they may never be able to crack the n55 which is what BMW wanted and tried to do all along.
