got a few ?s

i have a 2000 f350 with a 7.3 it has a bb turbo and a ts chip, i have done the 6637 mod and i put the filter restriction guage back in and my truck will still suck the guage to replace filter if i get on it. how can i give it more air? Next ? if im driving along and a low speed and hold the petal still the truck will surge it does not want to hold a steady rpm driving below like 35mph through town but it does not do this all the time any ideas as to whats doing it?

How much fuel is in the tank when it surges? The stock fuel pickup in the tank tends to suck air when it get to 1/4 or less. Mine used to to that until I did the Hutch mod in the tank.

Where is the filter minder?

If it's tapped into the filter neck, it's going to suck the minder down every time, even on a brand new filter.

You don't need the Filter Minder anyway. Just change the 6637 when it gets visually dirty. Mine in a land fill somewhere... LMAO!!!

It sounds like air in the system somewhere, but I have also heard of problems with the throttle sensor causing similar issues. Drive by wire is great until they start going bad.
Some one else will chime in soon for some more insight.
