Great device

Reviewed By Justin S (CANTON, MS) —4/23/2015 8:27 AM

I removed the muffler on my Vmax to get that nice loud sound without having to spend any money, and it does but when it kicks in to V4, it drones bad and rattles the whole truck. This was an easy fix and is much easier than an INtune.

Life saver

Reviewed By Daniel A (SANTA CLARITA, CA) Reviewed for a 2007 Chevy Silverado —4/22/2015 9:32 AM

GM knows this is a problem yet they have not recalled these engines. I feel I purchased the Range device In time before any major damage was done, I installed it and ran high octane fuel and some injector cleaner and my truck has never ran better. I don't notice a difference in fuel expense. I hope it works for you.
