Ecu

Ok,
I got a 95 GSR (built so far for all mtr). I am running a new set of pistons, Type R cams, and everything on the motor has been replace for speed. Unfortunately, I still have the factory ECU with no a/f piggy back on it. I am thinking that if I was to put on a new computer (Gude, Skunk2, etc) i should have gains in HP just from the fact that they would be built for performance. I would like to go with the Hondata ECU (for ease of control), is that a learning computer, that will tailor the air and fuel for my motor for the best performance? Also recommendations for ECU's would help (preferably with DYNO numbers not just opinions).
