I've been working on a MAF conversion and have a prototype which should be in production in June. I have it running on a 3.2l Metric mechanic M20 and will adapt it to the M30 also.

Each version will come with a custom EAT chip for the specific motor.

Here are a few pictures:

The M20 now has much improved throttle response and driveability. You can actually accellerate from 1200 rpm in 3rd or 4th gear.
