As the title states, I'm wanting to add around 100hp to my 2013 gt500 and the idea is to do a TB, tune, ane upper pulley. I would also like to know peoples thoughts on the best parts; I've been around the block enough to know you get what you pay for and that some shops are not worth their weight in brown stuff. That said, I was thinking about the Ford racing dual 65mm TB, lethal performance tune, and VMP stainless 2.4" upper. Thanks in advance for your input.:beer:
