Been using this product for years. Two 94 GTs and now on my 04' GT. Never fails to increase performance as promised. Would buy it again...Thanks

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!

in my opinion it's one of the best things you can do to open up your performance in your vehicle once you've done the Exhaust upgrades and cold air intake you can see a big boost in performance I can even sure from now and all 5 gears
