Default EQ - Borg Warner EFR 8374 Build, Prelim Tune - 500whp with a lot more to go!

This car has been in the works for quite some time now. We finally got it running and got some break-in miles on it, so I spent a couple hours with it on the dyno to start making some power. We ended up cracking 500whp with just 24psi but ran into fueling issues so kept it there while we re-wire the dual pumps. Either way, this car is FAST and spool feels amazing on the street. The block is built to hold over 30psi and 8000RPM, so we have a lot left to go
