    Great people to work with. Got me in on a tight schedule and the tune really improved drivability and MPG. Definitely would recommend 💯

    OVtune 2.0 for 87 octane. No performance gains, but revised shift points and throttle sensitivity. And both of those are drastically improved, which is all i could ask for. Very pleased so far (couple weeks in).

    If you have a stock taco, get this done asap. Even with my setup and all the extra weight I carry plus the 33s I was getting about 14 MPG, after the tune I am not getting about 17, and have more power and torque. Great and friendly staff/owners. I highly recommended to use Desert Armor for your tune. As well as light pod and RTT needs.

    Got to speak with the owners during the tuning and they are great folks that are passionate about off roading and the outdoor life.
