Install was not real easy, I had to update the software multiple times. Allow plenty of time to do the initial install, took me about 2 hours. Can't believe the performance improvement over stock. Haven't checked yet to see if any improvement on gas mileage (didn't buy it thought for gas mileage). Well worth it.

Reviewed By mark W (Everett, WA) Reviewed for a 2015 Chevy Silverado —7/29/2015 2:54 AM

I bought the EDGE INSIGHT so I could read what my truck already knows. Install was a snap into my 2015 Silverado 3500 duramax and now I can view my EGT without drilling so I know when it's safe to shut down when I'm towing. Pre turbo EGT isn't available but I'm able to use my non-towing EGTs as target temps.
