Injector Questions

[blueovalman14]

Hey Ya'll:

Its been awhile since my last post but need some advise about my 2005 sd.

I've been having this mis-fire/funny vibration from my enginge when i'm in 5th gear and under 2000 rpm's, cruising. I'm taking the truck to a mechanic friend to get a contribution test done on it next week and i have a gut feeling that multiple injectors will be going out.

So, the question I have is: What size injector could I upgrade to while still using the stock turbo?? What type of power increases could i see with proper tuning and fuel mods??

Thanks!

You can run 155's with the stocker. You will also need a fuel system

What kind of power improvement could I see with a set of 155's with the fuel system & proper tuning??

Which company would you recommend looking at injectors from??

I am not sure on either of those. I havent really looked into it.

I ran 190s no issues. Thats about the biggest id recommend and you can still tow with a good tune. 155s will get you to about 500 with good tuning and a turbo upgrade, 62/70 or modded vgt.
