i wonder if anyone can help iv allready posted this plee for help on the legacy forum but no joy. i have a 94 singlr turbo legacy (charge cooler) with dual boost baileys dump valve and rising rate regulator my problem is i suddenly seemed to have lost power, the engine will reve to the red line ticks over fine boost gauge goes up nicely, but no coresponding throw you back surge, its like it starts to boost then runs like a non turbo i have switched the dump valve no difference. the only thing i touched was to change the oil to castrol edge 100 miles before the problem occured i have now changed back to a 5w oil could it be blocked lifters? low fuel presure or dump valve or electrical maf etc, ? i dont really know where to start there are no warning lights on and car runs fine just feels like very little boost
