Trimalyzer is great but you'll need to tell it what format your MAF table is actually in for its data to make any sense. I haven't looked at an 0411 so I don't know what sort of MAF table it uses, but on a '95 Corvette's stock PCM I had to create a brand-new MAF table in Trimalyzer that matched the Hz values found in the factory BIN, at which point it was able to offer corrections based on my logs. My guess is that's where you're being tripped up.
