Maybe Agnem can pimp his pump builder for some info for us. I've played with mine before only to notice more or less smoke, no power increase noticed. Also the torque screw is on pumps from 92.5 on up.
I will probably wait until I have new injectors and the timing set before I mess with mine. I do believe I found it though. The screw on my pump sticks out at a 90* angle just above the round part that all the lines come from and has a anit-tamper cap on it. I think thats it anyhow.
Yes, but it only limits the metering valve until the RPM's reach a certain point.
There was a Stanadyne Tech article posted here a year or so ago. The Low RPM Fuel Limit was explained in it.
The pic is of a DB4, but the header clearly states DB2 & DB4.
Well, I cranked mine out a fair bit this morning. didnt make a difference around town except more smoke when I walk on it. Tonight going down the highway my truck had way more get up and go at 130-140kph compared to how it used to be.
it limits the metering valve till the gov starts pulling it away from the screw.
I noticed a little seat f the pants change too. I haven't installed my butt dyno or anything, but I would like to see what it does on a set of rollers.

It smokes too much and raises the EGT's to be of any use towing, or racing...unless you had a cyro cooled intercooler and some compound turbos. Then I am sure you could play with it just a little.
I am going to set mine where I had it yesterday and take a video of what it does, so everyone that doesn't know, can see exactly the amount of smoke we are talking about here. It's definitly bad for the engine!
Ok, I dont think my pump has a torque screw.
You must be registered for see images attach
The screw would be above where the injector lines come out. I can't see that area in your pic.
my truck is a 92 so i dont have torque screw right
