Yes, not done yet either, will post results in my other thread later. Picking up 120+ intake air off headers which skews cf 3 or 4% (shop was 85 or 90), built a inlet duct to pull air farther out and lower intake temps. Repulling and tuning soon

Was coil, fired it up today, started pulling with stock.module that worked at end of day, breaking up again, does it early sometimes today, isually IF module gets hot and goes haywire its at high rpms. Swapped dui coil on, pulled flawlessly.
fashioned a air duct to get cooler air away from the headers. Been tuning, well past 700 hp w biggest pulley.
