FYI the "Germans" are back to true twin turbos in the respectable cars. M6, 550, etc. and the m6 runs like a rape date. The more mainline cars like the 650i, 328,335,528 etc are singles

For one do yourself or your buddy a favor and put the .91 back on it, two get he back pressure sensor installed back on it. I have less displacement ( 6.4 ) and more turbo ( 71 ) and stock fuel with no spool up issues. The 6.7 should spool up a 66 like it anit ish.

The computer looks for a back pressure signal though to determine the amount of fuel to deliver, so with out that the computer has no idea how much back pressure is being made.

That would be a better question for Matt @ Gearhead.
