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!

I can tell a noticeable increase in horse power. Which was much needed for the 4 cyl. I really like the way the transmission shifts now too.Haven't noticed any increase in mpg yet. . In short I love it. Matter of fact I even ordered one for my jeep the next day!!!
