Most Popular Yes - California Approved for Chevrolet Silverado 1500

Simple to use with easy menus and update process via your computer. Don't expect a dramatic power boost with gas engine. I have noticed much improved mid range throttle response, especially at higher elevations. My 2500 HD no longer has to downshift 2 gears to maintain or increase speed on 5 to 6% grades in winding turns in the 45 to 55 mph speed range. Wide open throttle passes at higher speeds seem to be a bit quicker. To soon to form any opinion on fuel mileage.

Thank you etrailer for your awesome customer service. etrailer will be my go to site for all my automobile needs.

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.

Great Parts, Good Price, but pretty slow on delivery.
