Hypertech 8000 PowerStay for GM and Ford

This thing does exactly what it supposed to! I was having issues when it was dropping into 4cyl mode, but this thing keeps all 6 going at all times and no more problems from my truck!

Works as advertised. Replaced a Range unit that failed.

Works as advertised

The product did not work for my 2024 Silverado tray boss 6.2. I tried 2 modules neither worked. Tech support said it might not work with my application.

Works well. Plug and play.

Biggest problem reading reviews is that very few tells us what vehicle that it worked on. I have been searching for one that works on my 2020 Silverado with 5.3l motor and 8 speed transmission. Most don't work with this model and newer because these vehicles are DFM. Well I bought this with a 50/50 chance it would work. Opening the box and reading the before you install card, it tells you to go to Hypertech web site and update the Powerstay module. Well the only thing I found wrong was the the card with instruction does not match the web site. Had to call tech support and they told me how to update. You could never do it by the installation card in the kit. Now using it! Works absolutely perfect. My truck does not shut off at stop signs or red signal lights. Next drove the truck at 55 mph were there was no demand on the motor. This would enable the DFM and you could feel the engine vibrate. Now it no longer does this. So I would definitely recommend this product, due to perfect function and cost. I can't as of yet state what happens to mileage. I expect a 1 or 2 mpg less but just haven't tested it yet. I hope this helps others out.

I updated it online before installing it. Throttle response increased,

Plug it in and forget about it. Does everything I needed it to do.
