They're alright for stock turbochargers as you can see about 22 psi on one.

For tuning sake, a Bosch is LOADS better.

The boost compensator is 2 turns from being all the way in I could back it off a turn ?

Max revs screw already done

If I wind the max fuel another 45 degrees the pump will shut off , I don't know how much further I can go before it does shut off tho , does anyone know? Shall I just go in ten degree incruments till it does then back it off 5 degrees ?

Ahh okay so I'll never get more than 22 psi I might as well wind the actuator all the way in then and control just with fuel its wound 5 turns in ATM

I know a bosch is way better iv ran one on my 205 and there so easy to tune In comparison but I just want to get whatever I can out of this Lucas

Also temp gauge is starting to rise when I put my foot down so might take the stat out

I gauged the compensator with the amount of lag the turbocharger gave. It's trial and error, but you will get to a sweet spot where the turbo will spool harder and earlier. Some Lucas pumps (luckily mine did) can be wound all the way in and not struggle to start, so again it's trial and error, if it does, back it off a little bit.

As a rule i use fuelling to control the boosting. If you're limiting the boost and getting smoke ON boost, then you're not burning properly. It's best to just wind the wastegate all the way in (K14) or shorten the bar as much as possible (T2/GT15) (or just fit an MBC). This way the turbocharger can only create the same amount of boost for the fuel being injected. Don't worry too much about over boosting or anything, like i said on a stock turbo they don't tend to go over 22-24 psi.

I ran a TD04 with a welded wastegate on a Lucas pump and it actually went surprisingly well. The Bosch is just a lot better for compensation on boost and fuel that can be delivered when you need it.
