Has anyone put out a write up on how to tune for a FI application?

not that i know of, BUT

if you are running with the MAF:
first of all N/A get your MAF table in line with your commanded fuel (PE based on rpm) change the MAF numbers using a wideband and make sure that it is dialed in correctly.

with FI you can use your MAF and your PE numbers and just change your PE numbers to say ~11.5 from lets say 2800rpm and up(say you hit 5lbs of boost at 3000) up to around ~11.8 at high rpms(or lower if you want) talk to several forced induction guys and see what AFR they are running

if you are running on the stock pistons, i sudjest lowering spark(timing)
