I'm planning on doing a tune on my 2013 CL65. Knowing that stock bypass valves are not likely to give me proper control over boost I wanted to upgrade.
Weistec slaps their AMG tax on their parts and dings you $700 for their super deluxe whooshing BOVs that make your car sound like the fart piped turbo Honda.
I prefer a more mature stock sounding units.
Turbosmart has the answer either way. I picked up these internal bypass valves for less than half the Weistec price.
But thats a blow off valve and has no control of your boost whatsoever. What your looking for is the wastegate buddy
Not entirely true.
Wastegates control the boost. Bypass valves allow it to bypass when you let off the throttle. When they start to leak you lose boost pressure.
My car is 9 years old with 115k miles. I replaced them while the engine was out for turbo coolant seals.

Valid point, I've just never heard of a bov failing like that before. You did mention control of your boost and not maintaining boost, hence it's the wastegate your looking for. I been thinking about disconnecting my wastegates and just running full boost. Should be fun, I'll let you know when I try it

Just an update. I installed a manual boost controller and boy oh boy is the car fast. Too bad now I'm chasing misfiring problems with my 2006 s600. It's a love/hate thing with the v12. Love it when it's running right but hate it when it starts misfiring. Even though the misfiring is due to maintenence but it's pretty expensive to remedy. I wonder if the diaphram inside my wastegate is still in good condition. The car pulls hard but since I don't have a boost gauge installed, I don't know how well the boost is holding.
Hank you need to contact the fellow in California who makes up a voltage transformer with fuses and improved components as well as coil packs that will live.

I had no problems. They were replaced preemptively. We had the motor down to do the turbo coolant o-rings so it was an easy swap.

Brucewayne I have been in contact with Clark for the last couple of months. I bought his boost box and sent him both my coilpacks for repair. Before I sent it to him driverside bank was misfiring. When I got it back passenger side bank was misfiring. I bought a voltage transformer from fcp euro and it was still misfiring. Put the boost box back in and found that 2 of the leds didn't come on because of blown fuse. Replacing the fuse didn't help. I sent the boost box and passenger side coilpack back to Clark. Clark said the,coilpack had no issues. So hopefully the new boost box he sends me will fix the problem
