318rwhp =>~ 350hp....depending on drivetrain loss.

Yep - that is the right way to do it. At some point I'll go this route. For now more driving lessons will be money better spent for me!

Similar results for the 987.2, or does the 981's new intake setup make a difference?

Not my car but a friends 3.4 981 Cayman S tuned to 380bhp on mustang dyno. (Mustang= conservative numbers) Similar numbers from 981 GTS as well. Plenum upgrades showed no improvement whatsoever. Headers needed to achieve 380BHP. Doesn't matter if it is a boxster or cayman, S or GTS these engines will tune to the same ultimate hp.

My plan is off road headers and tune. Any recommendations on combo including the tuner? It is basically a street where mid range torque is somewhat more desirable . Thanks. Kevin
