Are you in Cali or something? No such thing as costing more for performance work, LABOR IS LABOR. labor should be around 65-75 dollars, maybe less depending on where you live. Depending on the shop, might cost around 800 at the most. You can find as cheap as 500. Hell do it yourself and save the money for something else, maybe an intercooler. It's not that hard, as long as you can follow instructions. Vortech should be very well written and I heard that KB has the most detailed instructions.
