Review on 🚀 High-performance Chip/Power Programmer for Hummer H3 3.5L, 3.7L, and 5.3L - Boost Fuel Efficiency, Save Gas & Increase MPG, Enhance Horsepower & Torque! by Mark Jefferson

So far everything is fine, I installed it according to the instructions and it seems to be working fine. It should be noted that not all of the computer's RAM is returned at once. I installed it, took it for a quick trip to the store and found that my remote control locks didn't work and my driver's side side window didn't work. I drove further km according to the instructions (15-20 km) and everything worked fine.
