whats the deal with these boost dependent fuel management units? all the boosting ive done ive had the stock ecu remapped for boost and used a FPR tuned to 50-60psi and have had no problems. im finding a vortec fmu for a 100 bucks everywhere, what other things go along with this to make it work. it would make my projects alot easier. please throw yer 02 at me thanx
