‘92 Chevy Blazer, ‘86 BMW

I had the system installed on my ‘86 BMW and got an astounding 38% increase in mileage and a dramatic increase in horsepower which is very evident going up hills. I was so impressed with this system that I had one installed on my ‘92 Chevy Blazer also. Got a very impressive 32% increase in fuel economy on this vehicle. My transmission doesn't down-shift anymore in going over the mountains on my way to the coast.
