as for a TB the stock 60mm already flows better then it should with stock manifolds but 65mm might give you gains on a light modded motor but if you plan to do your manifolds,cam,head and really build you'd prob want to upgrade to a 70mm , udp will prob shoot you around 7 or 8 hp, cold air intake and exhaust dont really add all that much they allow your motor to breathe better though which will pay off in the long run but you will get some gains maybe around 5hp from each you prob noticed with the exhaust you lost some torque down low but gained some up high UDP will help give you back all you lost down low though doing headers you prob look at around 10hp gears and t-loc wont give you any hp gain but they're really good to have and will definitely increase your times , 3.73 for 5spd, and 4.10 for automatic is most common as for the chip it all depends on how you get it burned or custom for your vehicle or whatever so i really cant tell much for that but for everything but the chip if you add it up look at around 186 from a rougly 150hp starting point
