How are you doing? I have a LB7 with EFI, 4in straight, Turbo inlet horn, Turbo drop pipe and a PPE turbo boost value. I'm looking to get some more work done like getting the LML manifold put on. But I have been looking for a list of DIY or cheap mods to get rid of restricted parts on the truck.(anything for better air flow or fuild flow) I currently have 290,000 miles and I am looking to push to at least 700k miles. Thank you all

 

i have posted a bunch of little write ups on here for lb7s, how much rail pressure and pulsewidth are you getting from your efi live tune? actual numbers from logs not desired numbers from the tune

 

I'm getting 28mpg in my duramax Lb7. I have the Poe tune on luv 5. You need to feather the throttle at times not to melt the trans. Banks intake, 4" straight and intake hirn too great truck

 

At idle I am getting 5.5kpsi-6.0kpsi rail pressure and I'm not sure on how to find pulsewidth. Can you explain on how to find that number
