MAF or Speed Density (PRO's & Con's)
Undecided what I want to run with my twin turbo setup. My car 88 TPI 350. Would like to know the benefits and hassles of each system and some of your expierences. Thanks

more prom board related..
Go straight over to the Prom board.. You'll get more info there.
However..
Skip the MAF... use a 730 or 749 ECM and $58 SyTy code. 2 bar is stock, 3 bar available, also available source code version $60 (A assembleable commented version of $58) if you are wanting to make hard code changes.
I've run a 749 and a 730 with $58, (there are a couple differences between them, mainly an additional injector driver in the 749) with a twin supercharged sbc for a couple years.
I'm also using the same setup in my SVO and F100 project truck.

What are the cons to a mass air setup? Just wondering. If fuel flow is regulated by the air sensor and the tables can be modified....can't you get better results?

Problem being the code maxes out airflow. Once you hit 255 gps the code maxes out and at that point the MAF no longer is an active part of the equation..
Going speed density, gives you up to 28 lbs (3 bar) of boost/airflow..
