No major problems with it

Reviewed By William K (Chicago, IL) Reviewed for a 2003 Chevy Astro —11/23/2011 6:11 AM

Instruction manual was incomplete; did not have my Astro van listed. Called help number and they helped me. Can't really feel any difference in performance. Haven't checked gas mileage yet.

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.
