Amazing

By George G on May 12, 2020 | Verified Owner

If you’re looking for a cheaper alternative to tuning your car this is the way to go. I tried it on my 2015 Camaro SS and instantly noticed the difference. That annoying sound that you can hear after a muffler delete is gone!! The power is just there at all times as well! I definitely recommend this product.

I can finally enjoy driving my Camaro!

Bought this because the cylinder deactivation was really frustrating me. It would always turn off the cylinders when it wasn't appropriate. This completely fixed the issue and I'm so happy!!!

Fixed my problem

I recently straightpiped my 2015 corvette. When it automatically went into v4 mode it sounded horrible. I ordered my afm/dfm disabler and got constant updates about it. Got it the next day after I ordered it. Literally just had to plug it in and now it stays in v8 mode and sounds amazing. Got quotes for a custom tune to fix it and they wanted $800. Thank you very much.

Awesome product

I recently had an exhaust put on my 2021 RST 1500 Silverado and when the AFM would kick in my truck would sound like a Subaru and not that true V8 sound so this product was recommended to me by a friend and I bought it right away put it on the truck as soon as I got it and it is awesome definitely does everything as advertised on the website from throttle response to better fuel mileage and just having the power of 8 cylinders all the time 10/10 recommend!

Works Good!

No complaints here. Plugged it in and sure enough, no V4 mode. Stays V8 all the time. Love it!

Excellent product

Bought the range for my 2008 5.3 Chevy Silverado. Went from using more than a quart of oil between oil changes to using none. Went from 15 miles to the gallon to 16.1. Engine runs great and have not had to have a tuneup in four years. Highly recommend it. I am buying one for my brother who just bought a 2015 GMC with the same motor.
