Well I know it took a long time but the turbo is on, Nothing is changed but the turbos, It is still street tune 18 pounds of boost, The boost I would say this turbo boost just a little quicker than the 66, I haven't tried to blow the tires off but you can tell it is making more power, Drives great, Am very happy I got this turbo so far, If all goes good will take it to the drag strip Friday, The guy that is working on it is going to drive it to work and do some hard pulls and see what happens
