Wow ! I'm totally impressed with this item and cant believe the amount of performance that was wasted prior to installation. Definitely recommend you get one too...unless you are to worried about some tree frog in the Amazon's and think you might get a half a mile more to the gallon without it. But if you are a true blue red blooded American that knows just what a hemi is supposed to be like get one today and deobama your ride ! God bless America and have a great day !

Installed on 2018 Dodge Challenger V6, certainly has upped the fun factor of the car significantly. In 18 months of ownership, I've not spun the tires more than twice. After 3 days of ownership, it's happened much more often, many times, by surprise. Doesn't make the car faster, but makes it feel faster and much more responsive. I caution all to be careful in the higher modes. Can't imagine any other throttle response product is significantly better to justify 2 to 3 times the price point.

It’s a little sucker but works! Just installed and did a 14 hr drive and it saved my right foot from lots of pain from the normal extreme foot mashing to get it to go up hills and shift sooner. My 17 ram hemi loved the throttle response which in turn gave great shift down response. Few times tranny banged hard because it kicks down sooner but ECU will get used to it. Great for the dollar. Happy with it!
