Few weeks ago I decided to swap out the standard trans fluid with ams oil. It seemed to make a difference right off the bat but then as I drove it more, not so much. Possibly even worse, hard to say. Anyway, I failed emissions yesterday, or my system monitors weren't ready and found out the easiest way to get through this was to put the stock air cleaner box back on and return the tune to stock. I did that and drove it around about 40-50 miles or so. One thing I couldnt help but notice was that this thing was dropping into every gear with complete ease. Almost to easy . I started thinking, could it be because the RPM's match up better with the stock program in between shifting; as opposed to falling quickly if you dont shift it pretty quick? What the hell gives?
