No problem. Base Holley hp/ dominator software is the same. Hp just doesn't have all the features enabled as with the better unit. Sniper and terminator have their own. I'll look and see if you can do the firmware add on. But it wouldn't matter as you said we both can do the math on the sizing issue. There is no way a prv will idle with that much injector flow. Best bet for diy owners is to build off megasquirt unless they want to pay for a professional package.
