Orange cv713

So under light throttle like coasting at around 1200-1400 rpm I get a miss but it goes away with more throttle and if you go down to a idle it goes away and I don't know if it matter but every now and there is visible smoke that comes out of the exhaust at a idle and it just smells like raw fuel

No I have a manifold and s400 off a 2000 R model

So do you think the turbo and manifold will work without upgrading injectors I have talked to Rochester and they recommend injectors and I understand I could get more out of it but I honestly am okay with the power I have if I could really use it with out it heating up so I feel like adding more fuel puts me back in the same boat and I understand etec motors have a different more desirable power range and I assume that's in the timing and fuel delivery in the tune file so would my computer accept a tune file for a etec

So I have a cv713 dump truck with a Ai 427 and a t310mlr with 4.42 gears and live in the mountains of Western NC and it does pretty decent if you can keep it the right power range but I always feel like I don't have enough gears I am a Eaton guy so I fight with the transmission more than I would like to admit but my biggest issue is I fight egts all day pulling mountains and hills and I constantly feel like I don't have enough gears so I took the resictor muffler off and straight piped it and that did definitely helped some and I know I need 5 inch exhaust I have the down pipe part number from grand rock and the other piece raneys sells but I have a manifold and turbo from a etec motor I was wondering can I put that on without injector and still spool it and make decent power and could you put a file from say like a etec 460 or something on it
