2015 Supercharged High RPM Sputter/loss of power Clutch/Gas?

Yup rev limiter. Now your steering column left gauge looks like is giving you the air to fuel ratio (AFR) readings, but I’m not 100% since it’s moving kinda fast. Look for it to show the numbers mentioned above. I may also add that when coasting (foot off pedal) you may get higher readings. If you don’t have one installed I’d highly recommend it. Search the supercharger thread and you’ll see several ways of accomplishing this.

 

It will usually peg the AFR gauge when you lift throttle, or when coasting off throttle. What's happening is, the ECU is cutting the injectors as an economy measure. The engine is basically windmilling until you touch the gas again. You can see the same behavior on a MPG gauge, it will peg at whatever the max reading is.

 

LAWLS.... is OP serious? Does OP have a 3rd gen... cus this seems like a 3rd gen crowd question.
