Good read and great data, so from the sounds of it I should take the roto fab intake off the zl1 go back to stock intake with your drop in maybe run some e20 and see if I get any codes. Maybe I’ll hit up Jesse and do a comparison on his dyno using 91 with this roto intake vs your drop in (if airbox is same as your c8) and then try dumping a few gallons of e85 in and repeat on the stock map.
