I have an ats 088 turbo on my 6.9 and like I have read by everyone I was only hitting about 5 psi, 7 up a hill maybe a bit more after pushing really hard. This was after I turned the fuel up 3 flats, rebuilt the turbo, and wrapped the up pipes. I figured this was normal.
Now, I readily admit I am a ******* and since owned the truck I had been meaning to take some slack out of my throttle cable because I wanted it higher up off the floor. Any time the floor mat got under the pedal it was like I could get enough fuel. So last night just for the heck of it I looked at the top of the pedal where the throttle cable slips in and there was about 1/4" of slack. I slipped on a split ring shaft collar for a 3/16" shaft (like $2 at Ace) which is about 1/4" thick. I then needed to run to the grocery store. Holy ****! I had to keep my foot out of it from going over 12 psi under 3k. I called my wife to tell her and after hearing how she does give a **** but she is happy I'm happy I went home with goose bumps. So the new project will be turn the fuel back down to keep my egts in check. Not too bad now but probably too much if I ever tow something.
Anyway lesson learned, make sure your pedal is actually opening the throttle all the way. Oh and in case you have seen my other thread I still do have a tick but I since I've been using stanadyne's additive it's been quieter, still there but quieter.
