At the top of my list I was thinking:

325 to 330 Mass air sensor transplant $300. Benfer or ECIS intake $150-300. Greddy engine management piggy-backwhich has setting for mass air sensor upgrade $325.

These mods combined would yield close to 20HP.

I dunno the research you did on the greddy thing, but computers such as the BMW ECU will often "adapt out" piggyback systems; not sure if it applies to your application.

Also, check your PM!

here is what he said though

I'll chime in on this since I've tried the unichip on my 330. You can tap into the crank sensor and if tuned properly, the idle is smooth. The problem when I tapped into it was the 4.7K resistor which was indicated but a 5K trimpot was recommended running at 4.21K. After a while, this resulted in a fried crankshaft sensor.
