What would you suggest??
Grind your own plate?

Springs?

Adjustments?

All of the above ? And what else?

So you ground the afc foot to be parallel with the back edge? Did you grind the front edge of the barrel so it doesn't hit the housing?

Is the stock afc spring too stiff for effective preboost fuel tuning?

I'm considering pulling my plate but I'm pretty sure that I want Some kind of preboost fuel control. I don't want to bog off the line but a little smoke is ok. With the plate pulled in my 180hp pump, the afc foot/arm will be the next limiting factor under full throttle, yes? That's when I should look into grinding the afc foot and barrel? I'm not planning on opening up my timing case, so will that mean the Mack plug isn't something I should order?

Right now, Ive got all the smoke down low but it clears up at full boost. I'm wondering if getting enough fuel for a slight haze at wot/top end will be attainable on the stock turbo @ 38psi and stock inj/dv.

Don't buy one, add a flat washer to what you have.

Never tried running a stock turbo so I can't answer that.
 
So much info. My head is is spinning trying to digest this stuff. I'm a visual person- can anybody point me in the direction of some good exploded diagrams that correlate to plate position and AFC arm position/function?

thanks
 
ok so this overflow valve... im still trying to get more info about it.. where's it go and whats the advantages of getting one??? and what are your guys 1/4 mile times with a stock trans???
 
FINALLY! After a couple of days of reading and lookin at pics im finally understanding how to tune these pumps(think my head is about ready to explode with so much info). Thanks to everyone who has helped out!
 
StainlessRRA posted a link to these in another thread. I forgot about them till I saw it.

you already have one. it is the bolt that holds the fuel return line to the pump. it has a spring and seat inside it to control fuel pressure in the pump. take the spring out and strech it or add a stiffer spring to make more fuel pressure.
 
They're great pictures, I look through it almost everytime I do any minor pump work. I'm glad he's got it all in one place for us!
