i went with cp and an injectors clog up on me really bad for a while. enough to make me run almost on 3 cylinders. ran like that for over 500 miles to get back home gave it hell with some 10 psi boost just to get it home. and when i took the pistons out to go back to stock they were still perfect. and i had predet a few times really badly and it showed nothing. i love mine

 

i dont see how cp pistons made your injectors clog up
