i did what you told me,i flipped the washers,ground .090 off the back of the barrel,and i set the star wheel at 20-25lbs. of pressure.i put it together and all i can get out of it is about 7lbs.of boost and no smoke at all!what do i do,this thing is sick!

when you hooked the air up to the afc it was moveing before you put it back in right? what kind of press did it take to make the foot start to move? you may have to loosen the wheel up a little bit.

i just took the housing off and reset it,loos like when i put it on the break-off bolt(which is still in the pump)was under the edge of the afc.pressing the foot hard against the fuel plate.i put it back together and it works fine now,started freaking for a min!does that sound like something that would have caused that?

so the arm was hitting the fuel plate? if the afc can't move it will hold your fuel back

also when you set your afc press did you set the arm to start moveing @ 25 psi or go full open @ 25 psi? should be full open @ 25 psi just makeing sure I didn't confuse you

yep,write that down in your little book.you seem like one of the more knowledgeable of our group,but even the best get stumped sometimesit does spool much faster,but still a god awful cloud,and egt's hit 1500 in 4th gear.

ok so when you first put the hammer down you say it does spool faster? and now with a modded afc and your 0 plate you are almost @ full rack travel therefor you should have more fuel up top ... all you need now is a bigger turbo and the rack plug
