Chris also brought he his Lightning to be tuned. His cobra has a 3.1" upper pulley, catted X pipe, catback, and was previously tuned. After some tweaking it made 461RWHP/474RWTQ. You don't have to spin the stock blower very hard to make power, its only when you get into the ported blowers that they really benefit from a upper and lower combo.
