I'm thinking of swapping my Pro-M 75mm MAF (calibrated for 24# inj) for a 90mm LMAF. I'm installing 60# Siemens Deka injectors and will need to have the sensor calibrated. So I have 2 questions: 1. What wiring modifications will I be getting into? 2. Is it as easy to have Ford calibrate the MAF as it is with Pro-M (simply mailing it in to them)? Also, what other mods am I missing? Will this require an adapter plate?
