looking into getting an EMS... which one are you using?

[HPR]

I'm looking into getting a new EMS for my car but haven't really decided on which one to go with. I would like something that has built in boost control, 2 step launch control, fuel & ignition control (of course) and capable of switching to MAP to eliminate the AFM.

It doesn't matter if its a piggyback or full standalone. As long as it does the above features I mentioned and datalogs as well. If you're running something similiar, let me know what you think about it.

Some systems I have had experience with are A'PEXi PowerFC D-Jetro and Autronic. Both are appealing, but I would also like to hear about the AEM and GReddy e-manage ultimate or anything else before I make my decision.
