I researched this heavily. If you really want a step above RedEye go with Whipple Supercharger5 for Gen 5 Hellcat motor. Gets you to a 3.0L blower from a 2.4L Hellcat or 2.7L Hellcat Redeye blower and has this massive, dual pass, dual core inter-cooler technology for twice the cooling area of any other PD SC for Hellcat 6.2L.
As you change the pulley sizes, there will be a point where the more boost you create and you put thru, will be past the point of any more HP gain, because the intake manifold temps with stock setup. Boost increases, intake temps increase and HP stops or drops. So it will be a little playing around around with your exact upgrade components and tuning, plus the TRX air-box.
The last time I checked, HPTuners was the only one that had unlocked 2021 TRX PCM. My shop uses Diablo, so just waiting on that to occur to start.
