look at my mods below. regardless of the pulley, i only got 7 lbs of boost at 5100rpm and 380rwhp and 396 torque on the dyno. After the 5100 rpm power drops off. I have all stock ignition. My car also sometimes feels like the hp is flat between 2-4k rpm if i punch it sometimes. My tuner was telling me its becuase i need some ignityion upgrades like the 6a or 6al (i cant remeber which one it was he said). He also said, my car would be a totally different animal with these upgrades. Makes sense to me but I want to hear you guys experience as well. My main thing is the 2-4k rpm. I guess it just isnt gettin enough flame with the blower and h/c/i being all stock. thanks fellas
