turbo boost pressure ?

does lengthening the actuater rod increase boost pressure or decrease it ?. alan.......

you can shorten the waste-gate actuator rod and increase the boost. You may need to remove the actuator and cut a bit off the end of the rod to allow sufficient adjustment in the sleeve portion (don’t take too much off at once – better do it in 3mm increments !). What you will find is the rod is too long to get more boost, as too much of it screws into the sleeve and bottoms out. You will have to shorten it quite a way to get more than 1 bar boost – but this is often all you need. 200 Tdis run at 0.7 – 0.8 bar – you can safely increase this to 1 bar – 300Tdi’s run at 1 bar already – best left alone!
