I would definatly recomend hondata or something simular.
With that much money invested and your goal you shouldn't risk it with half ass tuning parts.
Upgrade your intank pump for a higher volume (255lph) pump get some larger injectors (800cc +) look into an aftermarket ignition such as the msd and then of course hondata.
Sounds lke you have done your research.
I would recomend the gs-r oil pump too.
