Howdy,

Does anyone know how to increase the total boost pressure on a vacume based VNT turbo system.

We been trying on an 1995 Audi A4 1.9TDi, no such luck as yet.

:innocent:

Dont, these turbos are weak and will fail.

From what I have read the stock system runs at 13psi and they can be safely increased to 18psi.

I have now also discovered that the only way to really accomplish more power/torque is a remap, I have a unit for flashing the ECU but not been able to get it working correctly yet.
