Riddle me something.

Thanks! Kevin came off the dyno Saturday at noon and hasn't stopped smiling yet!

Nasty Girl made #2 only 652 RWHP on a single stock LB7 CP3 right after the motor and twins were built....and no twin turbo tuning had been done. That is on regular #2 fuel you buy at the station. 800hp on an engine dyno on #2 only with a single cp3 does not seem out of reach for any of us.

Racehemi has been reading AFR on his truck since the day EFI got released. He has some very good data!

Then how come most tuners set the gas motors up at ~12:1? Not saying your full of it, just for the sake of discussion.

More gas being delivered gets you more power. Pretty simple.

A gas motor runs much better for power in a richer/lower air/fuel ratio, but emissions get all nasty.

That part I figured out. Most tuners I've talked to set it up around ~12:1 because it's a safe range to fend off detonation and running lean.
