[QUOTE="IA Shelby, post: 13224299, member: 122099"] My 11 did 552 with 2.59, jlt123 and cjtb on 91 octane. Reality is that the CAI and TB only added a small portion of the rwhp. They are great when you start making big power. The factory exhaust flows well until you start getting over 600 rwhp and that is where the shine compared to stock. The pulley and tune will get you a similar bump to an 09. The reason you can get 100 rwhp from 09 is that approx 40 is credited to adding a CAI. So in essence you picked up 60 from the smaller pulley and tune. A pulley & tune on an 11 with the factory cai can also pick up 60 so when comparing apples to apples they are the same. My 11 did 654rwhp when I added the VMP TVS with 2.5 pulley. I would call VMP and just go straight to the TVS. [/QUOTE]
