Best Jeep Wrangler Performance Chips

Great product and price.

After looking at many options for a way to change the speedometer of my 2015 JKU Rubicon to accommodate the larger tires that were on it, I finally settled on the Superchips Flashcal F5 3571. I watched for months, hoping to catch a deal on it since I wasn't very excited about spending my Jeep budget just to fix the speedometer. I finally found a deal that I could live with at etrailer.com. Their price was well below every other option. I was informed via email that my order would ship in the next 7 days. I had already waited months, so not a big deal for the price. 3 days later Brittany called just to let me know that they hadn't received the item yet, so it hadn't shipped yet. I really appreciated the personal touch, even though I wasn't expecting the order to be shipped for another 4 days. The order arrived 10 days after ordering, well packaged and just as advertised. I read the directions, connected it to my computer and installed the latest updates. I then connected it to my Jeep. Like the instructions said, I measured my tires (my 35s actually measured 33.5") and entered the information into the Flashcal. I also changed the DRL settings so that my headlights come on. My tires are aired down, so I was wanting to shut off the TPMS, but much to my surprise there was an option to change the TPMS level. I had read all kinds of reviews and watched videos, but that option never showed up. I was thrilled to say the least! At this point, I grabbed the GPS and went for a test drive to check the speedometer. It is now spot on and a hidden benefit is that when I changed the tire size, it automatically changed the shift points. My Jeep drives so much better now! I really wish that I hadn't waited so long to make this purchase!! Full price would have been worth all of the benefits that it provided.

First off, GREAT PRICE from etrailer. The product itself is a must have if you have larger than stock tires on your Jeep Wrangler. The programming is smooth and seamless. 5 star company, 5 star product.

The Edge CS2 won't pull the PID list for my van, so I just get to see the standard PIDs/guages and cannot update to additional PIDs. Not what I was hoping for but it's good with those standard PIDs. Not sure it's worth the price for MPH, Temp, Voltage, and RPMs.

I wanted CS2 to get eyes on my trans temp in my 1997 Ford Powerstroke XLT when I am hauling my camper. When the product arrived (a couple of days before I was expecting) I hooked it up to my computer per the instructions. One easy to follow download and twenty minutes later it was ready to go into the truck. I went out and plug it in (note: the OBDII port on my truck had a black cover on it and was located on the passenger side of the transmission hump under the dash) it would not power up. Hit the trouble shooting guide and it said check the cigarette lighter fuse. Bingo that was the culprit. For reference on my truck it is the #16 fuse which is the fuse in the upper most right hand corner of the fuse box under the steering wheel. So far I have been happy with the product. I have eyes on the trans tempt and new goal to see my truck produce 20lbs of boost (note the CS2 insight is only a monitor and will not help me get closer to this goal but it will let me see it when it happens). I was also pleasantly surprised with how stout the window mount was for the unit. It solid and holds the unit steady allowing you toggle threw the menus with one hand.
