My best 1/4mi numbers with MAF:
13.6sec @ 103mph
Best numbers since converting to SD:
13.5sec @ 105mph
These numbers are after my swap to a T56 trans and I still totally suck at launching, the A4 really had me spoiled.
You need to burn chips to make SD work well on a modified engine. MAF will run reasonably well without tuning, but you're leaving some HP behind if you don't get in there and match the fuel/spark tables to your engine.
I don't have a CS degree either (Biology actually) but I can read, and there's plenty of material here on thirdgen.org and on diy-efi.org.
