kalmaker has a custom OS you can buy to do it. It was rumoured there was a free version in development but I dont think it was finished. Generally speaking the MAF tunes are more than capable, so if you still want to do it for your preferences on stock hardware it has to be kalmaker.
Have you read the FAQ? For lots of information and links to significant threads see here: http://pcmhacking.net/forums/viewtopic.php?f=7&t=1396

A common misconception is that a Mafless tune is better then a MAF tune, This is simply not the case. The MAF and MAP sensors are only a way to sense load/airflow, and calculate injector pulsewidth. I think this misconception comes from the LS1 tuning, Where the MAF on VT-VY were small and restrictive, with the ability to use the backup speed density system, its general practice to remove the MAF and tune with the MAP.

Im pretty sure that the1s Enhanced bins can measure 13,500hz which is 16500mgc. Twice that of a factory ecu. off the top of my head I think that's near 15lbs of boost depending on the engine.

So max power, would be the same as MAP sensor tune, And Thats all dependent on your setup.
