dude... this is like any other fraud out there saying you could just Turbocharge any car without tuning it. It's a heap of crap. Don't buy it, don't install it. It will only give them money for a piece of scrap metal. DO NOT EVER BUY IT OR EVEN CONSIDER IT. Sure they might even add on a motor for "2lbs." of "psi" which i've seen put on an IS300. He went to the track and his trap speed went lower and his time went higher.
