Chasing a Ghost here.... Not another BOV ?
So I am only building 10psi with my 2 Rude and my supporting mods listed below. I had a 15/20 pitched down 3mm pushing 7700 RPMs and purchased a 15/22 and now only 7350-7450 RPMs. I also purchased a Rotax Racing ECU off a member here but can't tell if its legit other than it bounces off the rev off load at 8600. I have the piggy back removed bc when installed I threw a check engine light.
My question is my Tial BOV opens at partial throttle, is it suppose to do that? The only time I hear it open on the water is off full throttle. Could this be my problem?
Let me note that with my s3 charger, after a fresh rebuild I was only hitting 7400 and thought it was the piggy back missing but it was there. Had it hooked up to BUDS but kid at the dealer was clueless and didn't know if he had to do anything to correct it, I thought it was automatic. Also I got the 2 Rude from a member who just had it build by Jerry, looked mint, so I never questioned the slip. I was told by someone else, who is very repuatble here, that many times these charges aren't torqued enough and slip bc these wheels are heavy. Is this true as well and could be the cause?
Help from this site is always appreciated!

A rude 2 should be producing more than 10 pounds of boost. I think closer to 14 or 15 Pounds you need to check slip sorry to say not sure were to set it though.

Your slip should be a little more than the max boost your charger can make. But I dont think that is your problem.

rpm's seem really low

You are building boost in the right RPM range. The amount of boost is obviously low for your set up. How are you checking the amount of boost that you are making? Is your gauge right?
