This one uses a Rennix EFI system with a GM type 1 bar MAP sensor. The sensor itself isn't capable of seeing beyond 1 psi or so of boost - it hits its maximum voltage at that point. So, if you don't switch to a standalone ECU, you'd need some way to add more fuel and pull timing when the ECU doesn't see the boost.
