stock pump settings or as close as ?

Hello

I'm after putting my pump back to stock.. Previous owner had fettled but not very well now I want to re do it.

After the relief of seeing the plastic cap Is still on the main mix screw I was wondering if I could stock the star wheel under the diaphram . I can find stock on the diaphram so that's no problem , but surely there must be a way to determine how far down the shaft the star wheel sits .

Can any one also tell me what soley adjusting the star wheel on a stock pump would do? Bring boost in quicker and lower in RPM?

7mm standard or 3mm after tweaking I think may be the figures you may be after? There are comprehensive details with photographs how to tune 200 and 300 TDIs below on a link I posted elsewhere. This may give you an idea how to roll it back perhaps or get it how you want it to run? Good luck.

Thanks K9F from reading that would you say the 7mm is meaning the underside edge of the top cover once it's sprung up?

That is how I read it!

Either way if you take careful measurements and mark things up yourself before 'fettling' you will be able to revert back to where you are now and be no worse off. If you go through life with your head in the sand....all people will see is an ar5e!!
