Same year and gear ratio, except mine is a manual, and I use the Pedal Commander (not familiar with Pedal Monster) and really like it. I have found it to make a huge difference in throttle response. It’s not like it improves the acceleration times or top end speed (I say in jest) but it’s certainly noticeable in feel.

 

Banks Pedal Monster.. I have run for 2 years on the 21 Mojave.. Yes initial throttle response improved significantly .. no issues .. I don't disconnect when going in for state inspections and warranty; MY local dealer service dept mgr and techs are cool performance dudes. Keep that in mind if your relationship isn't cool with your dealer for warranty work.
