Has anyone tried a tune to upgrade between a MPI 325 to MPI 340?

Based on the spec the motors look exactly the same, aside from the max RPM. if that's the case, you should be able to unlock some extra HP on the top end with a tune. I found this tuner that claims to do the job.

It would be interesting to try although I'm not sure if I'd what to be the guinea pig, but maybe there is someone out there braver than me .
