i dunno if this is any help but i got mine tuned with a hks one at 11psi exhaust, 34smic, intake and lightened flywheel and i got 199kw which was a shock considering it was pretty much stock before. obviously in shootout mode so id take 10kw off but still a surprising figure imo i was expecting 168kw. picked up alot more torque mid range so the car is very responsive to drive. smells like its running rich and on idle it misses now and then dunno if thats to do with the exhaust cam though.
