The Pulsar is a piggy back tuner offered by Superchips/Edge products that plugs inline with your ECU, it offers stock, economy, tow and performance tunes and allows you to reprogram for tire size, gear change and ESS memory. They advertise HP gains and mpg gains and I will attest they are real. I got mine with only about 2,000 miles on my JT with 35's and before I added some of my accessories I have now, I could get 20+ mpg in the economy tune easily. Since going to 37's on stock gears, I am using the tow tune and getting 15+ mpg, so pretty big difference, but most of my driving since 37's has been in town with not a lot of highway. I actually think highway and consistent no stop and go driving would be back in the 17 mpg range. But I plan to re-gear. Still haven't decided between 4.56 and 4.88 though

Are you running the pulsar on a 2020 model or a 2021?

It was a 2020, just sold my Gladiator a few weeks ago. Ordered a diesel Wrangler that just arrived yesterday. Going to pick it up Monday.

I did the same, my High Altitude on 35" with 4.546 gears, runs MUCH better.

Hey Binford, I have a 2022 High Altitude on 35s as well and just booked a regear appointment...BUT, based on everything I've read, I can't decide between 4.56 or 4.88. I pull a 5k pound camper about once a month so I lean towards the 4.88 but don't want to go too far.

If you could do it all over again, would you still do 4.56 or consider 4.88?

Exodus 4x4 is one of my local shops, they also have a youtube channel and are partnered with AMW4x4 but this is what they recommend for gears on their website. I still need to regear mine as I am on 35s with 3.73.

Yes my tires are 35.1 tall
but I did notice this weekend that my Tazer didn’t update to 4.56 it still was programmed to 3.73.
I need to recheck the rpm now. I tell you it shifts and performs much better with the right gear ratio programmed

True tire height rarely meets what the specs say. Best to measure your actual diameter and base your tire height adjustments with JScan or Tazer accordingly to your true tire height, if you haven't already.
