So now I've got the Big Hoss bundle installed, & it seems I want more HP. Is there anything else I can do without having to go the ugrade turbo route and/or getting into engine internals? Also, as budget DOES NOT allow, I can't get into propane or nitrous(yet). What's next? Would a cold-air intake significantly increase horse compared to the Banks/K&N air filter? Does a pulley kit exsist for the '99.5-'03 7.3? What else can I do!?!? Going back to the whole 'upgrade turbo route', what I mean is I don't want to replace the turbo completely, BUT; I would consider component upgrades. I already have the Banks Compressor Wheel & Big Head wga. Are there upgrades for the turbine wheel or impeller shaft? I know Banks offers the Quick Turbo turbine housing. I'm hankerin' for more power!
