They were only able to get maybe 575hp on a max effort N/A build. However, by utilizing a whipple 3.3 kit, they are able to "trick" the PCM into supplying enough fuel for proper AFRs with forced induction....

I would rather stay N/A if possible, and it sounds like this plugNplay harness you're working on would solve the fueling issues.
