Ok yes yet another cam post didnt think we had enough...but anyway i cant decide between the tsp220 and the tr220 im not looking to ever run any spray or boost just want a solid 300 to the ground with a nice lope and honestly dont understand what the difference will be between .551 and .581 performance wise i will probably go with a 112 LSA(unless advised otherwise) it is a daily driver also...any input will be appreciated
