You can't base the calculation base on a stock 2.5L 165hp engine and a stock ECU.  Lets assume that the stroker 2.6L Suby with variable cam, built heads and high performance ECU has the same state of tune as the base Cayman 2.7 L 245hp car.  This is an assumption but the calculated power is 227hp for the Suby.  I'll take 227hp.  I would also argue that an aftermarket tune for that 2.7 L Cayman would likely be higher than 245hp.  I personally think that its conceivable that this high performance aftermarket Subaru engine is good for 240hp.  Call Greg.  Talk to him.  He's installing lots of these engines.  I'm sure he has a good idea of the performance.

Ok. So we're going to use the J.C. Whitney logic that each tuned "thing" adds 10%?

It doesn't work that way in the REAL world. There is no free lunch. Each item that is tuned/tweaked adds power but as the state of tune goes UP there are diminishing returns.

There isn't a whole lot more to be gained in a Cayman with an ECU flash as the engines are vario-cam and in a very high state of tune already.
