Hi I'm new to the site but have learned so much and hoping you guys can help me out. I've been getting a dead pedal at 53-55lbs of boost, things I've done aside from power mods are auto to nv5600 and 2001 fuel filter with twist off cap. Power mods are on my profile. I've replaced apps, map sensor, made sure the quadzilla is good, have good fuel preassure, and great power till that specific boost. Any ideas would help. Thanks.
