BTW...ladedruck is load pressure...It's what RUF calls their adjustable boost control.....

I'm glad you explained what it meant, but I still don't know. Sorry.

Well...I know it interfaces somewhere in the turbo boost configuration...don't exactly know where or what it does...but the performance sure is enhanced....

What it does is borrow positive pressure from the intake plenum and apply some of that positive pressure to the normally-vented-to-atmosphere port and its isolation diaphragm in the wastegate. The diaphragm acts on the wastegate's boost spring to prevent it from opening at its nominal/normal pressure. The higher the pressure on the normally vented diaphragm is, the higher the boost pressure needed open the wastegate.
Bottom line - more diaphragm pressure, more boost, more compression, more fuel, bigger bang when something lets go.

You have to place a tee in the line before the WG. You then run from the new tee to (the inlet of) your gadget. The other line from the gadget (the outlet) goes to the top port on your wastegate (what was the vent).

Thinking about it, I see no reason why you couldn't tee off of the brake booster line or the line to the aftermarket clock replacement gauge (if you have one) if you wanted to.

Oh, it works by letting an - adjustable by you - amount of pressure back on the vent of your wastegate and therefore increase your boost pressure before allowing the wastegate to open.
