I still don't think his tune is all that safe. They probably leaned it for more power, but it's pulling -22% near redline. That's lean as FUCK. At least they didn't fuck with the ignition tables.
He's been debating doing the 2 Wheel Dyno Works ECU tune and ripping the power commander and healtech module out. I think he can probably sell that stuff to cover some of the cost of the tune. Plus, the 2wdw tune kicks your fans on early. He agreed that's the best move.
