What kind of tune are you trying to accomplish? Tow, performance, economy. This tune has some very serious mistakes, and could possibly ruin your rig. Check out Dieselplace.com for some tunes that others have done and compare what is changed. Make small adjustments and then log what changes.

HOLY CRAP!

Wow, I would not put that in your truck...

What are you trying to do?
Pulse width is crazy, that will not work.
vain position, what are you trying for there?

I'll just stop there....lol

How about modifying the area you are familiar with by a tiny percentage and see what they do for you. You can run the same value across the table like that, its not going to do what you want, Some tables this works but not any you have tried. I dont know what else to say lol.

begin with a stock tune, and change one table only, with your reasoning, there are several on here that will help you, that are very good LLY tuners.

B0720 and B0721 is a good place to start, though not my particular strategy, it has been very successful for many.

Hey KB, if you dont mind me asking what your strategy is? I am also going to PM you.

It took me a year of just playing with trial and error, before I finally came to the conclusion that the truck was inconsolable with the existing fuel pressure table. It is a refinement nightmare. I looked at all the box tuners, and not a single one of them makes any real effort to refine the ride experience this way, so I took nearly 2 years to re-invent the wheel.

So I build tunes around a fuel pressure histogram that I wrote. It involves an awful lot of work, but the end result is sooo rewarding, that a 500 HP vehicle can also feel like a lexus in part throttle.

The specific issues addressed with this are progressiveness, noise level, and economy.

I never did this with the intention of selling it, but it seems I ended up with a marketable product.
