To start, Titan DP and bm3 Stg2 91 OTS tune. It’s been on the car running with no issue for almost a month now. Drove to dinner a bit ago and everything was fine on the drive there and back. Get home and start pulling into the driveway and notice that throttle response is much slower, slight change in engine volume, almost as if it was running in limp mode, but no CEL or messages on the dash. Go to check codes, nothing unusual. Try to reflash the map, no change, but when I got out of the car to try and lock it and shut everything off, the alarm immediately starts going off. Again, no dash messages or anything, but when I unlock it, red LED in the rear view is constantly flashing. Decide to flash it back to stock, no improvement, problems still present. Finally go and reset the DME, now it’s all back to normal. What the hell?! Anyone else ever experience anything like this??
