If you don’t have one, GET ONE! He says the power is instant, no lagging anymore and fuel mileage is better!! He didn’t notice a difference in fuel mileage right away but after using it for a few weeks, he said his fuel mileage has never been better! I read some reviews to unplug it as it drains your battery. So far he has never unplugged it and has never had an issue so let’s hope it stays that way. Buy it, you won’t regret it!
