Inexpensive Power

Reviewed By JOHN J (Fremont, NE) Reviewed for a 2000 Chevy Silverado —10/28/2016 1:18 PM

I have only used the 87 octane setting on the unit, but definitely noticed a little extra seat of the pants power. Also the transmission shifts are a bit crisper. Haven't checked fuel economy, been having too much fun! You really can't beat the bang for the buck here!

Installed this in my 2006 Ford Expedition. I set it for 87 octane fuel. It really woke up the engine performance and I am seeing 2mpg better in town and 3 to 4 better on the highway.
