Review on 🚀 Range Technology Green AFM/DFM Active Fuel Management Disabler Plug & Play for GM Vehicles RA003G by Troy Simpson

Man I did a lot of research and spoke to a few people before making this purchase and I was never disappointed. Reducing 8 to 4 is a cool idea but useless. I checked my mileage with 2 tanks of gas before and 2 tanks after and I lost absolutely nothing to the MPG! I have a 2018 Silverado 4x4, the average mileage per 400 miles is 19.7. I think the best I have is 22-24 on the freeway 280 miles round trip. You will not regret it.
