unfortunately Tony, I believe your issue lies within the programming and the only way to cure the problem is with custom tuning. The fact is, the DME was programmed for exactly the way it was in the 740 and and in more than just a few ways you have changed that. You have taken the beast from it's environment and now you have to program it to think differently. Save yourself some frustration, time and money. I would at least call Dinan to get their opinion. These guys are better than the BMW's engineers who program the factory software. Just some friendly advice.
