Well over on the stoc there are quite a few running stage 3+ on rs injectors,some have even been on a rolling road with no problems,superchips have confirmed that you can run 440 rs injectors on there stage3+ file,if it were the injectors it would go into limp mode after a while and it does not,but i think your right for the sake of an hours work i will refit the standard ones and see what happens,your link is for stage 3,there is also a 3+ .
