fuel injectors for 06

playing with the new truck today and found an edge ez installed. now im thinking my firm shifts are from aftermarket tranny parts, but i wont know for a week or two when i change the fluid and take a look.. .here is the question if i decide to do injectors who makes a decent performance injector tip that is reasonably priced for the 06 cummins. someone said i could use the edge ones from ebay. i thought they were for the 03-04 trucks any advice guys
