Repeat after me ..
I will NOT hack the
I will NOT add any "unmetered air"
I WILL recalibrate the system to an MAF with higher capacity and
larger injectors ...
Yes, it's a lot of work, and after a few YEARS, I finally figured
out how to do it with Bosch Motronic systems .. but once you do it
RIGHT, you'll never do it any other way!

PS: If anyone is trying to do this on a Motronic System .. let me know
as I can probably help you do it ... I'm adapting EVERY darn air-volume
(flapper) BMW and Porsche to nice mass-air sensors :)
