Overpriced for what it does

Change.Tire sizes and shift point

So for context I am using this on a 2013 JKU Rubicon 10th anniversary on 35's with 4:88 gears air intake and throttle body spacer. I owned a jeep off road and rockcrawler shop for years in a different time in my life so I have been around this industry working on nothing but jeeps for some 35 years. The programer is very easy to use and updates were a breeze via laptop. Being able to change both lighing options and more so speedo calibration with larger tires and the flexability of tire choices was key. The settings showed a noticable improvement when moving though the fuel setting and the throttle response in the 91 octane settings showed more snap to the pedal in real time. Menu's were easy to follow and load times were relatively quick but the gains immidiate. Clearing the syste also was easy in the event you need to sell the vehicle and had no check engine lights or diagnostic issues at all on either install or removal. SUperchips is a a proven on point company and with the many items out there I feel this product has the best gains for the money spent.

I bought this to adjust the speedometer on my 2008 Jeep Wrangler that I put 5:13 gears and 35" tires on. Programmed in the parameters and the took the Jeep out for a test drive, way off. Adjusted tire size up and down and couldn't get the programmer to make the speedometer read within 10mph of actual speed. Called tech support and was greatest by Niel or as I now call him No help Niel. Described my situation and asked for some suggestions on how to proceed, Niel told me I needed the tunner and a computer so he could log into the device. I told him I don't have a computer to log into with and asked if there was anything we could try without a PC. No. That's the only answer he could give. I explained I go to work before the call center opens and am working well after they close and wanted just some pointers for when I get off. No. The guy had zero desire to help. I asked what it is I could do when I get home, plug into a computer and try... No. So you either have to schedule your day to be at a computer and wait on hold for tech support or get NO help. Thanks No help Niel. I was going to upgrade this unit but now I'ma box it up and get a tuner from another company that works through my cell phone.

I measured and then set, but still not right so I decreased 0.25 and it worked ever since. No more traction control warning.
