I'm thinking of possibly stroking to 2.7 then doing cams then supercharging it that should yield 200+ kw atw
I would hope I'm keeping my eye on this !
Is there anyone who has stroked their motor on the forum?

Interesting one we found on Bomberlegacys Raptor 08 Legacy was that there is engine load limiters on the 2.5's based on RPM, which seriously restrict power or driveability. Anything over 1.5g/rev was ignored so previous tune needed heaps more fuel at 1.5 to account for fuel needed at say 2.2g/rev. Once lifted, could be run leaner was a smoother torque delivery at all rpm and throttle ranges. 1.5g/rev on a 2.5L is around 0psi boost so no surprise why Subaru had this logic in the ECU!

Interesting, west_minist of X-treme Racing Tuning was having issues with Subaru's ECU logic when he did my tune. He was also having trouble with the engine load. I'm not sure on the exact details on the problems he encountered and solved but in any case: it's great to see the successful development of tuning. I find it astonishing that the Denso ecu is so versatile.
