This is a must have for 2017+ rides that have a locked out ECM.I bought this one for my 2019 Silverado Custom Trail Boss(ignore the description,it fits many vehicles) and one for my 2017 Camaro SS.Best word to describe the REACT:Awesome.You get wide open throttle at just a touch,meaning that the throttle plate opens all the way instead of gradually.There are unique modes to select and they all feel different.Install is easy and tidy.Get one!

I really really struggle on off-road without such Throttle controller. This product is not cheap, but it worth the money. Crawl mode is a killer. That slow response if huge deal especially for JK with stick. In this mode I was able to make Slick rock trail without a single problem. Huge deal for me!
