Sure, what engine are you trying to use it with? I use this exact tuner for my 04 Duramax

search around for one that would work best for you though. I just watched a bunch of YouTube videos and asked friends lol.

I put one of these in mine.

https://www.amazon.com/Commander-Throttle-Controller-Bluetooth-2007-2017/dp/B07NDXYN3R/ref=sr_1_fkmr0_2?keywords=pedal+commander+pc+29&qid=1572533430&s=automotive&sr=1-2-fkmr0

It's not snake oil it actually works. It does NOT create horsepower. It just takes some of the drive by wire lag out of the system. Definitely more responsive off the stop and feel more like the power it should have based on the specs. MPG takes a small hit. I run it on basic city mode and mine is the older non bluetooth model. So it was cheaper. I run 180 miles a day down I25 in CO for my commute and it was worth every penny to me to not feel like I was going to get run over anymore. Sport modes are fun to play with for 30 seconds but it's not a sports car so it just makes it really jerky.

​

Edit: I had a 95 XJ with the 4.0 and based on the patriots 175hp rating and XJ 195hp rating I always felt the Patriot should feel more responsive. Now it does.
