Electronic blow off valve
 

I'm in the middle of changing my car over for E85 and adding a slightly bigger turbo, the 54mm from ZZP. The turbo has a vacuum controlled blow off valve instead of the stock style electronic one. Has anyone deleted the electronic blow off valve? I would assume something in the factory ECU must be changed, but the directions did not call it out. It's getting a tune change so making changes will be easy if I know what is needed. Thanks in advance!

Hey, I looked at the z54 turbo and where the bypass valve looks to be mounted uses the same 3 bolt pattern as stock, so any diverter valve may work. I won't guarantee it, but it wouldn't hurt to shoot them an email to confirm.

I did contact ZZP but they didn't really know the difference between the valves function differences. Some research shows the factory valve is used in many systems for engine/trans/rear axle protection, so it's back in place!

That looks great! Glad to see it bolts on.
