travis, I would worry about the 12.2:1 is likely fine for sustained full boost.
all this talk keeps leading me back to switching to a standalone EFI system run my Esprit. Now, I just half to pull the trigger.....and really, really want to rewire the majority of the car..... :-(
I was just at the PRI (performance racing industry trade show), and there are plenty of capable EFI systems to run the Esprit. Looks like all will need a cam sensor if you want to run sequential injection. By today's standards......(even by early 90s standards) the GM system in the 4-pot Esprits is really outdated. From my understanding, the GM ECU doesn't even have the ability to adjust for elevation chages while driving. Must be a bad for those that live in mountainous regions. Apparently, it will compensate once you turn off the engine and restart, but doesn't adapt while cruising. Would be interesting to see the difference in A:F while driving from Denver to Vail.
Fortunately, I don't have those issues in Florida, but I'd still like full control over the ECU as I've never been a fan of generic chip tunes.
