LT4 fuel system isn't going to keep up @ .77 lambda @ E75+ @ 12+ psi. It's too rich and not enough fuel system.

Probably be mixing E60 @ .82 lambda for the fuel system to keep up.

I have tuned several of these cars now...so I have a idea in what these will tolerate.

Drop the e content to 60% and make sure you add the fuel pressures to your channels before next log.
