I have recently removed my engine and redone everything exterior to the engine. Minus a few components. I have the car up and running Idles great and is timed slightly advanced. Seems I still am on the slow side for power.....better than it was. I am wondering if the Turbo Pressure Converter Valve 7.21903.70.0 would cause it to be sluggish in its power? I am able to get 12 to 14 pounds for turbo boost but the car is on the sluggish side. I am going to unhook exhaust and take it for a spin soon....prior owner did that with no change. But the turbo was bound by carbon so who knows.
Wondering what the Turbo Pressure Converter Valve 7.21903.70.0 does as far as its function. maybe compared to the N75 which controls the waste gate. I need some more info on it.
All vacuum hoses and coolant hoses replaced. Vacuum Pump replaced and much much more.
Another question separate from those......Any site or reference page on what values are standard for these cars.....such as MAF flow, certain vacuum number to look for anything that shows up on VAGCom
