The R and S cars are targeted to run in power-to-weight or HP regulated competition series (Grand-Am Continental Tire Sportscar Challenge; SPEED World Challenge), so there's not necessarily motivation to increase power beyond what they are delivered with.
If you're competing outside of these series, or just want a track day toy, then yes, there are avenues to bump up the output.
Even within the last month, FRPP released a new set of intake and exhaust cams (different from what we already discussed) to amp-up the BOSS302's output.
