Default '08 FSR450 ECU tuneable?

Picked up a 2008 that idles fine, but riding it in low revs it barely lugs along. Without water it will then take off, almost like turbo just kicked in! It's not fun, dangerous.

I've cleaned, even replaced injector, new fuel filter and lines with clean air filter. Nothing makes a difference.

I'm thinking there's something wrong in the ECU. Can someone 🙄 , GGas dealers or others check adjust or change the efi mapping? I'm out of ideas.
