Once you have a bosch fuel pump you should get a good gain from a stage 1 tune.
What you want to do is get a boost gauge on 1st and see what you are boosting.
Then turn your max fuel screw in half a turn.
Take out the LDA pin and turn to the steaper side( im sure there is a guide on this), and remove the white plastic washer from under the LDA pin.
Now go for a drive and check boost. If you are not boostin 18-20 psi yet and there is lots of black smoke on full power you need to adjust the wastegate on the turbo. If there is no smoke screw in fuel screw bit more etc etc.
And if you are boosting 18-20 psi and there is lots of smoke screw out the max fuel screw tiny amounts until smoke is barely there. Just a light haze on full power.
You want to control boost levels with the wastegate and not the fueling if you know what i mean.
Hope this helps.
Darrens vids are well worth watching and there are lots of guides on this forum
