| I'm wondering if its those injectors. 740 is huge, but if your ECU is chipped specifically for them it should be ok. If you have a tectom you should plug it in and watch to see that the idle switch is turned on when you take your foot off the gas. I know you probably know this, but TT's have a different fuel pump than NA which I think provides a higher volume of fuel at higher RPM's, make sure you swap to a TT fuel pump if you havent good luck and keep us posted!
