not all VW's, vw's/audi's 1.8 turbo chips can add up to 50hp, and 50 ft lbs.
personally stick to the stock chip unless you have some serious $$ invested in engine upgrades!. chips usually give about 5hp at the crank, like .25 to the wheels, you will hardly notice a difference!!> Save your money and buy some CTR cams instead, you wont be dissapointed!
