Evo.brv problem

[sir boost a lot]

I have a 2013 m1100t and the brv bypasses on a hard pull and I loose power till I spike the throttle than it will seal and gain for a bit. I've double checked all hose routings, it blows off fine and works well under easy pulls. Next ill try the stock brv to see if anything changes. In a field with wide open throttle the boost will build than fall intermittently.

took it out again with the stock brv and problem solved. Guess ill send the evo in for testing.

Mine does the same thing and I'm waiting for the brass check valve update. There is an update for the check valve that is used in the 1/4" vacuum hose. The original kits came out with a plastic check valve in the 1/4" hose that would fail and has been updated to a brass check valve.

thanks for the info. I never rode it with the stock one before today and wow what a differance in power.

So have you lost power going back to the stock one?

No the power is great! a lot quieter of blow off though. It wasn't working right off the get go so I cant say if I noticed and less turbo lag with the EVO BRV.
