I still think 310's are overkill. Unless you plan on going over 10psi, the 270's should work fine. I do agree that the B&M and Vortec together may work, but I also know that Mallory make a single FMU that is adjustable for both vacuum and boost. It might give us the flexibility we need in a single package. I don't know what the best pursuit is, but I definately know that in general (especially during the hotter months) too much fuel has caused me to bog. Maybe by smashing heads we can figure out what is truely the best approach.

The 310's are only too big if you cannot dialout the off boost pressures down. Personally I think I'd just get 270's, but if I got a good buy on 310's, I wouldn't hesitate to use them, so long as I knew I was going to install the B&M command flow (which I am, just as soon as I get back home from vacation).
I just which those injectors where cheaper, they are so expensive.

What difference is the command flow going to make...I was out for awhile and think I missed something? Can anyone be more specific to the way it is to be used???

Regarding the 310s, if I'm going to upgrade injectors, I'm not going to do it a second time unless I make major changes costing major bucks. If 310s meter and atomize the fuel effectively at lower pressures (say 35psi), then I'd rather start and tune with them knowing full well I might get the urge to run 10psi. I'd rather not buy upgrade components with limits I might yet again exceed when stepping up things up just a little bit. Of course this assumes that they're happy running at lower pressure and that the car can be made to pass drive cycle emission testing with such a setup.

Lundgren? "...so long as I knew I was going to install the B&M command flow (which I am, just as soon as I get back home from vacation)." What's the scoop on the command flow?

I had thoughts of modifying my fuel line banjo bolt and the bolt that goes into the fuel filter. I am thinking of drilling out the core to a bigger ID to see if that helps tip in.
I figure that area has to be on of the biggest bottle necks of the fuel system. -let's face it, you can put in a mondo 500 GPH pump and it can only flow so much through those small lines.
I don't think that helps a low RPM bog, but for tip in and boost situations it can't hurt.
As far as injectors are concerened, I would go with the 270-310's and lower the idle/off boost fuel pressure.
I'll send a note to Zdyne too inquiring about the OBD II ECU. Pehaps if enough of us show interest, they'll look into it. hey? you never know.

CROM, the 255lph pump is adequate for 6psi and borderline for 8psi and stock injectors.
