I suspect the coils are weak. I remember in my old E36 M3 supercharged I changed the coils and plugs and noticed a horsepwoer increase of 25 to the wheels. Got better gas milage as well so I am thinking new coils ?? Spark maybe weak ? I just had a coil fail on me as soon as I drove from the shop
Anyone else with some ideas

Just for the heck of it, unplug the MAF and drive it around...see if the power feels better. MAF's degrade overtime and get more resistance in them, just like spark plugs. Cleaning them IMHO is pointless.
