the 42.5# injectors are almost maxed out when running a 2.9 pulley. when u run anything under a 2.9 pulley u need 60# injectors because anything smaller your engine is going to have no where near enough fuel to air. besides nobody will ever tune that with half a brain because its pretty much impossible. get 60# injectors man.
