any ine else in here I was thinking of taking injectors out and taking them to a buddy's tool and die shop and haveing them drill the injectors out bigger can this be done I understand that if it is drilled out I would have to mic the drill bit so I made the hole the right size let me know go or bad idea and if possible what size the hole should be for hp increases

I personally would have them removed and taken in to a shop who EDMs the tips. That's what I did. My buddy runs a diesel performance shop and he sends his injectors in to a shop and they took my stockers, disassembled them, EDM'd some brand new tips and re-assembled them. Basically took the stockers and opened the tip up to flow equivalent to a 370. They have since them been opened up even more.

I would not try and drill them out yourself. Once you see the size of the 5 holes on the injector tip, you'll know why. Just get the professionally EDM'd, you can't go wrong and you'll love the results. Oo.
