I was reading some EFI system descriptions. FAST looks good, but I couldn' find the direct answer to my question. They say it will run just about any engine combo you could build, including two power adders. So it's probably able to handle 5mm/hg.

I was also reading about the Big Stuff 3; that system has been gaining a good reputation in the last couple of years. It was interesting to see that this system can incorporate the GM flex-fuel sensor, and allow the computer to adjust for the varying quality and mixtures of e-85.

I would really like to use e-85 at the track, it sure would save me some money. I tried it last month, but my computer can't handle it.
