boosting not boosting

[wrx-wagon-rob]

have ya tried running the texaco stuff with octane booster?

Might help a bit....

Also try another boost solinoid to see if that is the problem.....

Maybe get one of the traders or another mechanic to have a look at it.....

Still on standard ecu and standard equipment?

Like you say boost solinoid could be the problem what would i pay for a new one?

Z4 ecu, problem was there b4 the upgrade /was told the z4 will run with the tdo4 turbo but is best buds with the tdo5 turbo

From your description i would seriously doubt its a fueling type issue.......

If the poor fuel is causing det the ecu will pull timing, if still detting it will drop the boost.
Agree mostlikely the boost solenoid but fuel quality is also v important and unwise to assume it is safe on texaco

Think its the boost sol anyone got one knocking about that could buy
