AFAIK, only Aquamist offers that, and even then I think it requires a standalone engine control system (so no love for L36 / L67).

Are you talking here about the MAP "self test" done on key-on that causes premature squirt? I expect to solve that with a second, dedicated MAP sensor.

I'll bet you're looking at between 0.005 and 0.01 sec difference between MAF and MAP response time.
