That's really odd. I test drove a 4.4i and a 4.6is later. The 4.6is had nothing to do with the 4.4i (suspension, steering, power, transmission, etc). Then I ended up buying a 4.8is. I didn't know about the resetting thing, maybe I'll try that, I do think however that my 4.8 has tons of balls and that's coming from an E36 M3 with a few mods.
