Query: WARNING

Don't bother looking at this product because it just doesn't work, in reality it made my suv slower than faster. Now I have made alot of upgrades to my suv like a gibson catback exhaust, weapon r cold air intake, a stage 2 performance chip, aem dryflow cone air filter. When the supercharger was installed I didn't notice any horsepower increase or torque, once I removed the so called supercharger put my foot on the gas pedal VA VOOM away I went. Another reason why I removed it because I was getting no power I research the some sites on the web and 99.9% were all negatives no positives. I had originally thought it was the performance chip, I first had a stage 1 mod then right when I had gotten the supercharger I upgraded to a stage 2 mod and I saw no difference until like I said earlier I removed the supercharger and WOW it really moves now. BEWARE remember do yourself a favor don't learn the hard way like I did, or you'll be out a few bucks while the seller is laughing with your money.
