You say you don't have insite or c a l t e r m software so you have no way of knowing what program was actually in the ECM before you flashed it with that DT90275.15, just because the sticker says that's the program thats in it doesn't mean anything at all. For all you know someone took that ECM off a different engine and then flashed it with the correct program for your engine...... whatever that might be.

This is a good example of why you need to always back up the program with c a l t e r m before you re flash and erase everything you had.

You need to find out what program is supposed to be in it according to the VIN, sometimes quickserve.com works for that. If not then call the dealer. While your at it verify that you have the correct engine and aftertreatment system for that truck. Who knows what kind of mismatched parts you could be fighting against.
