Just seen the dyno graphs! They are some of the weirdest looking A/F lines I've ever seen?

Where did you take it? Seastar Superbikes?

The torque looks about right though, which means it can't actually be running at 17.5:1 otherwise it wouldn't make anything like that. The spike in the A/F reading could be the AIS valve opening giving the exhaust gas analyser a false reading?

Was it blocked or not, that is the big question...
