Injector limits??

[dracing70]

So i am lookin for some input. I am curious as to what kind of success everyone has had with oversized injectors. What i mean is what is the largest injector oversize that has been used on a single modded cp3 duramax with stock engine and 2.6 charger, and was able to make run impressively with pulling duration out of the tune. Basically what is the cut off on a single cp3 and tuning changes???

I know a guy I have helped a little bit with a tuning issue that is running 45 overs but has a 85 % over pump and he can't hold rail pressure like he should. His lift pump could be part of the culprit but I would think less over size than that with your pump. It is all relative to what you find is acceptable in your opinion of performance etc.

I have heard terrible things about the II pumps... I run a WD CP3 and wouldn't hesitate running 60% overs.

On the other hand I run 45 overs with a stock pump and hold rail, just not a lot of PW.
