Superchips® Performance Chips Reviews

This does everything as advertised. Very happy. I went from tire size 30.5 to 33.9. My speedometer was off by a graduated rate that I had to calibrate with WAZE to know my actual speed. With the F5 tuner, I was able to get the speed consistent with the speedometer. The only drawback... it is in increments of .25. So I had to pick 34 diameter. But, now my mileage is better and I don't need the paper bag with the speedometer reading vs. the actual speed. This was used with a 2019 Ford F-150 3.0 Powerstroke

Went to several places to get my Jeep calibrated for oversized tires, speedometer reading 15 mph below speed, MPG was off 9 MPG. Anyway, it's a great product that does many more things but you can read about that more.

Great buy! Corrected the trans shifting and speed for larger tires! I can't notice the power increase but my fuel mileage went up. And any Jeep owner knows that's huge on these Jeeps! You won't regret this buy!

I wish I had bought it earlier! It’s a perfect programmer. I can say it for sure. It performs even better than I expected. The performance gains are very noticeable. Increased mileage and better throttle response. And the shifting is soooo much smoother. The programmer is relatively easy to install. The installation isn’t super fast, but I followed the instructions carefully, and everything works great.

Great product for that extra oomph. I didn't give 5 stars due to unlocked PCM doesn't come in at the same time as the tuner. You have to enter information of tuner and stock PCM and send in $1.00 to receive unlocked PCM.

Works great, easy to use.

Installed on 2008 JK Rubicon. Installation is extremely simple. Using this location is idea as I do not use this space for anything else as the compass and satellite antenna are under this cover. It is the perfect spot for the Trail Dash for both touching and displaying. I also took advantage of the tray area to mount a RAM base for the head unit of a ham radio. The price compared to others is great and the delivery super fast.
