I found there are a few things to periodically check to make sure youre getting the most out of your boost.
- Make sure the bypass actuator moves freely.
Check the linkage for binding or play. If you find the bypass shaft lockring is loose (Like I did). The shaft lockring is the steel spacer with between two teflon washers. This ring has a allen screw on the side.
To clean and lube actuator: A quick spray with throttle body cleaner on the shaft assembly to remove the dirt at the teflon washers on each side of the lockring and at the hole in the shaft lever where the actuator rod connects to it. Then a quick spray with WD40 or a drop of 3in1 oil at each teflon washer and at the hole on the shaft lever.
To repair loose lockring: First with the lock ring allen screw loose, close the valve completely by pressing on the shaft arm onto the stop. This is closing the valve with the spring action of the bypass actuator. You are not working against the spring of the actuator. Then tighten the allen screw on the lockring.
- Make sure intake is clean and leak free.
Make sure the intake hose has no holes or leaks at the clamps.
Also, a nice clean filter helps :)
- Vacuum leaks suck.
Use hose clamps or zip-ties on the vacuum hoses. This alone will reduce the chances of vacuum leaks and idle issues. Also make sure boost hose intact and has no leaks at the manifold or at the fuel management modules (and other vacuum/boost accessories).
- Whats worse than a vacuum leak? Fuel leaks!
Make sure fuel lines are leak free at all fittings and injectors.
