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!
