Ive been reading a lot about that Air Aid CAI. A lot of posts and good reviews. Tryin to save up to get one. Just went to glamis this weekend and was pullin a 16 ft enclosed trailer with a few quads and was struggling. Seems like they de-tune these T's a lot. The VK56 is a great power plant, just wish it wasn't so pricey to help them breath. Am lookin to do CAI, uprev and the full system from ol cajun
