hate to break it to you man but those vehicles are ridiculously hard to get loiud... i know guys with multiple world finals and titles that have struggled with these.. guy in my club isrunning 4 18s and 3x your power below the indow line ad not close to what you are going to need at finals to win this class... although they do very well in driveby.. i wouldnt expect more then a 152 out of it
