The Power Tune System will run you $3,599, a bargain considering the horsepower that you'll gain. For those with more heavily modified engines who crave more horsepower, XS Engineering offers an optional 400-hp turbocharger for this kit. As an additional modification, XS recommends installing a thicker head gasket (also available at XS) to lower the static compression ratio to take advantage of the higher pressure ratio turbo. The addition of the head gasket can yield 300-whp results with proper tuning and installation.
Staying on top of the food chain is not an easy task when everyone else is trying to knock you down. With the XS Engineering Power Tune System you can return the blows instead of taking them.
