No major problems with it

Instruction manual was incomplete; did not have my Astro van listed. Called help number and they helped me. Can't really feel any difference in performance. Haven't checked gas mileage yet.

hypertech max energy for 2013 chevy silverado 5.3

Reviewed By John E (BAKER, FL) Reviewed for a 2013 Chevy Silverado —9/24/2015 10:02 PM

It was a simple install out of the box. Plugged it in and went through the options and boom! Like a different truck. Only setback is I wish there was more information provided on setting the shift points. All in all you get the bang for your buck. It's a good programmer for someone like me that didn't want to deal with a computer and all the downloading involved in other programmers. Order, install, burn rubber.

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.
