I recently updated my Phase 1 627 HP supercharger to the 670 HP calibration. Since then the car does not run real smooth anymore. It has tons of power, though.
Today coming to work the " run power active" light came on and engine stalled. Anyone know what this is?
Help, please.

I'm not trying to be negative, but whenever my #8 piston started to go (both times, I've had two stock coyote bottom ends do it), that's how the car started to run. The little warning light and everything. It could be intermittent, but something in your engine could be quickly dying, like the #8 piston. Try reloading the previous tune man, see if the problem stops. Fingers are crossed for you dude.

I do plan on loading other tune.
I only have 1500 miles on it and I have never pushed it hard.
I hope its ok but it is under warranty.
