Are you trying to datalog when riding and tune the air/fuel from that info?
If not, it Needs to be dyno tuned, which would be better anyway.
You're not going to be able to just push a button a couple times on a piggyback fuel controller and tune a turbo.
Fortunately it's rich.

Have you tried running on one, factory, injector? It's possible you need a different controller.

Regardless, you Need it on a dyno.
Turbos are picky, and you Need an experienced motorcycle turbo tuner before you end up with a boat anchor.
