Edit Tuning related issue's Q/ about fuel guage Ok i'm having some tuning woes. My Ltrims seem to want to stay +2/+8 After the walbro pump install and 30# SVO injectors. It was realy rich right after, as you could gues. So i took 25% Away from my injector flow table. Then it was about 0/+2 in the L-trims. I left it there for a couple days to se how it would avg. Then i noticed my timing was getting 23* MAX. HMMM So went into the inj flow table and added another 2%. The L-trims were then at +2/+5% ! WTF!??! So I went into the pe/vs table and added another 2% across the board. The l-ltrims were then at +5%/+8% THIS IS KILLING ME ???? 
So anyhow i swaped my Tr55's for some tr6's today hopping when i get this figure out I can hit the bottle a little bit. And now them @%$#@% are like +9 and +10 sometimes. Something is fishy here. All these #'s are from my scanmaster
About the fuel guage thing. After i installed the Walbro my fuel guage has been stuck on E! I guess the float is in there wrong.
I need to pull it back appart. CAN this affect tuning?

Re: Edit Tuning related issue's Q/ about fuel guage I thought I read somewhere in my factory service manual that the PCM does a few weird things when it sees no fuel in the tank. One for sure was disabling the PO300 code.
