for now? its what I would be doing permanently.. keeping or replacing the solenoid is not going to fix the factory safety drop in boost. it is spiking with the cold weather and/or not allowing the car to warm up before boosting. mine used to do it all the time and it pissed me off. the only way to get around it is by bypassing the solenoid with a manual/electronic boost controller.
once again: problem solved.
plus i cant imagine the worth it:price ratio for a new solenoid, which is most likely not going to fix the issue.
