My last 2 tanks i got 11 mpg on my cammed full bolt on ls1.
But basically, I got my VE and MAF right on the spot with a wideband. Im commanding 12.8 richened to 12.6 through pe. I havent been driving that crazy.
It seems like there are quite a few people getting better than this with similar setups. I am going to give closed loop + reenabling dfco a shot.
Car is completely tuned up as well.
