Found the Cartuning Turbo Kit awhile back on 3800performance.com but didn't think all that much about it. It made 280Whp on a stock gt which aint bad when it comes stock with 160Whp. Now they have the kit for the L67 which gives a block of plate for the supercharger nose drive. Also available is an upgraded turbo which has a max output of 700 crank horsepower. Is anybody running this turbo kit? And is anybody running the upgraded turbo? Just looking for some dyno numbers on this kit.
