m5pwr:
My car is almost 1 year old and I have the Dinan CAI with the Stage II software. What you just described happened to me once (and only once) since I bought my car last June. I wasn't even under hard acceleration when it happened. I was just cruising along at around 65mph when all of a sudden, when I tried to pass another car, it was like it was running on 6 or 7 cylinders and 200 hp had vanished.
I drove into a parking lot, turned off the car... waited about a minute or so... started it up again....and the warning light had gone out and it was back to its normal self again! go figure? And it has never happened again since... I asked my mechanic about this and he said he had seen this a couple of times, and at least one of those times, it was on a bone stock M5. Therefore, it seems the culprit is NOT the CAI and associated software?...
This was the one and only time my car ever had any wierd happenings and it has never happened again. I dunno???
