1.8 t agu problem!!
« on: 02 September 2012, 21:26 »
Right!! My agu is running k04-001, Saab reds 3 inch maf and tip, front mount, 3 inch turbo back and a forge 007 dv

Basically it usually whistles and dumps quite loud, but seem to have droped a little power and nearly all of the whistle and dumping noise had disapeared. Any ideas?

Sticky dv?
N75 valve?

Was thinking maybe boost leak but runs and ticks over fine!!

Could a faulty actuator cause this?

It would cause a loss of boost?

Fuel pressures ok?  Weak pumps are common on stage 2 AGU/1.8T.

I have similar set up and mine don't waste at all. Saying that I still have the spring in the dv for standard set up which won't help I'm guessing?
