OK , I really debated writing this review. No, I didn’t buy my Gladiator for mileage but that doesn’t mean I don’t want all the mileage I can possibly get. I know ECU right? yeah yeah yeah I understand. I did not expect much from this. I have a gladiator Rubicon 1 inch level on 35s they are Mickey Thompson Baja Boss ATs. I typically sit around 13.5 MPG average. I drive a lot between OKC and Dallas. The only thing I’ve done “performance “ wise is a KNN replacement filter. That made no difference. I really thought this was going to be the same. It is not. Without changing the way I drive whatsoever I’m sitting at 15.6 MPG average and I’ve driven about 500 miles or so with it on. The drivability, the throttle response is significantly better. Look I know man I get it, You’re thinking there’s no way, I would be too. I feel like I’m taking crazy pills because there’s gotta be something I’m missing. I bought this during the summer sale so it was like 39 bucks, it made a huge difference. I really don’t know what else to say. I hadn’t done anything else to the jeep. Actually I put some skid plates on so I added a little weight. I’m not gonna sit here and say you’re gonna get a 2.1 MPG increase, I don’t know what’s going on there but I know this is the only thing that’s changed, what you should expect would be the improved drivability. It is just much smoother.
