Ebay GT45 + 5.9 Magnum + E85 blow thru

Any updates?
Got most of the Megasquirt wired and fired up the engine for the first time after chasing down electrical gremlins for a few days. Still need to wire a few more things, clean up and loom the harness and a few hundred other things and then actually start tuning. It runs super rich at the moment and I have a terrible exhaust leak coming from the block hugger header on numbers 4 & 6. But I swear, it’s not a Mopar without an exhaust leak!
