Was the bypass valve on your OEM turbo or aftermarket one?Didn’t fully experience it it caused a code. But I was told it was probably just my vacuum line but I had already put my stock one back on and didn’t feel like switching it back.
I wouldn’t recommend using it with the factory turbo. The piston is much more stiffer/stronger and is meant for higher boost applications which is probably why you got a code. Even if you mounted it correctly, RV6 said that it “might” cause a CEL, but can simply be cleared via Hondata. If you’re not pushing the factory turbo to its limits, the OEM bypass valve will be just fine.
