That will help you in adjusting it.

the alda is an altitude compensator. It limits fuel by the boost pressure sent from the intake manifold.

Yes, do the banjo bolts and adjust the ALDA.. also make sure the plastic line is not broken and if possible follow the line to the Over Boost Protection Solenoid. The rubber connector might be sheared or leaking.

(mine was and i just found out today after owning my car for a year.. no wonder my 0-60 times sucked... now its sooo fast)

I've posted this before....

ALDA = Atmosphärische Ladedruckanpassung = Atmospheric Load Pressure Adjustment..... or roughly in Automotive context "Atmospheric Charge Air Pressure Adjuster"

Abgasturbolader = Exhaust Gas Turbocharger

I do not speak German.....but I do read Technical German to a degree...and Blueprints, Hydraulic and Electrical Schematics.....

the word "Lade" is directly translated as Load.......but understanding German requires a bit of interpretation......so an "Abgasturbolader".....is directly translated as Exhaust Gas Turbo Loader......or in American English in Automotive Context.....Exhaust Gas Turbo Charger.......the loading being the "Charge Air"........so in Automotive context "Ladedruckanpassung"......becomes.....Charge Air Pressure Adjuster......

so although ALDA may be thought of as an Emissions device....by it's definition it adjusts the Fuel Injection Pump for changes in Charge Air Pressure....wether that Charge is Atmospheric (altitude effected) or Boosted via a Turbo or Super Charger.......
