For a piggyback controller that is OBD2 compliant (required if your in an emissions state) the Emanage Ultimate is very very nice. You can get a MAP sensor for it and using a piece of vac/boost hose it will eliminate the MAF like you want to. It has a 16x16 fuel map that is easy to map out yourself. Just tell it the a/f you desire and start driving it will adjust automatically to give you a safe tune.
As far as gaining power with one controller vs another one it will be negligible however you will gain a lot of troubleshooting ability with an Emanage Ultimate, has an anti-fouling feature, data logging, control Nissan Variable Valve System (S14 notchback, the NEO VVL , etc), and a lot more than any other piggyback system out there. I have been using them since first getting them shipped overseas in 2005 and I love the hell out of them!!
