Still cant be done on P10s, P12s should be able to do it if you run MAF only. Might have to rescale the IFR to get the needed MAF range if you're running high enough boost.

Really what you want is an 08-09 I6 with the 58x reluctor, run an E67 LL8 I6 OS and boost it. Can run up to 2.5 Bar with the factory OS that way. If you have an 02-07 I6, then Id suggest an 06-07 P12 running MAF only or swap crank reluctors for an 08-09 one.
