Review shared from Sprint Booster V3 Power Converter (19-24 3.6L, 5.7L RAM 1500)
Decent job
I bought this wanting to get rid of the delay between the pressing the throttle peddle and the throttle plate. There is still a pretty noticeable delay there with this on every setting except the highest setting, which there still is one, it just isn’t as big. The main thing about this device is the throttle plate opens up a lot faster once it does open up. I guess I was just expecting it to scrub the delay between the press and open.

Easy install!
Once I figured out how the connector on the throttle came off, everything else fell into place. Noticeable change in how the throttle reacts between sport and race modes.
