is was reading the installation directions on Scuderia. it seems some people have problems using the profec b with high boost. i will be running 15lbs on the high end & 10lbs on the end. is there going to be a problem, should i have gotten a diffrent controler?

The M2 ecu is tuned for 12 psi. I talked to the guy at M2 and he said that he recommends only 12 psi but the dynos on the M2 site were at 13 psi.

I wouldn't recommend 15 psi on your setup.

The Profec B has no problem running high boost. The posts you refer to mention a problem getting high levels of boost on the PRIMARY turbo only. If this occurs, you can hook both the pre-control and wastegate (T-them) to the solenoid instead of just the wastegate.

BTW, Mor is right. You should not be running 15 psi on the M2 ecu. 12-13 psi is the max with that ecu. You should really have an upgraded fuel system (which requires a PFC, Haltech, etc) to run over 13 psi.

Oh BTW, I just hooked up my Profec B Spec II last week and did the version that taps into both Wastegate and Pre-Control actuators. I capped off the hoses to both Wastegate and Pre-Control solenoids. I get steady 10 psi with little spike on primary like maybe 0.5 psi.

i do have in addition to the mods listed a high flow fuel pump (cosmo). the cars runs very strong the way it is. i'm running about 13.5lbs max now. i'm working on a used m2 lrg smic with an extra core brand new. i also think i need a wide band set up hks has a unit out looks good. more $$$$$$$$$$$$

The fuel pump upgrade won't really help you until you have larger injectors. And you can't run larger injectors without a stand-alone ecu....
