They don't list a PCIII for the 916, but surely the 748 one would work, just have it mapped at your local dyno.
Having said that, I have a FIM chip and a PCIII and there are arguments to fit both - the PCIII only does fuelling adjustments but is easier to find someone to tune, (and it enables you to fit a quickshifter), but the chip is at least capable of altering timing/rev limiter as well.
