im going to upgrade my turbo to a gt28rs, i am only going to run 7-8 lbs of boost, i have an afc, fmic, turbo back exhaust and the 626 intake manifold. Im just wondering if i need to step up to 440 injectors. Everything else runs fine with the stock injectors, im just not sure if they can handle putting out what the gt28rs will need. if anyone can let me know that would be a great help thnaks
