Not sure what banks kit you are talking about or what motor and year but you will get the same power with just changing the injectors and the rack stop if it is a 5.9 mechanical and will take about 5 hours if you can axcess the top of the motor easy. Ted

with that upgrade is smoke or egt an issue? how about fuel economy? Any idea how much cost would be or who to buy from? By the way it is 190hp w/inline pump and allison 4 spd trans. Banks power pack is rated at for additional peak 94hp and 214lb/ft at rear wheels but it shows test results that show 104lb/ft @ 2000rpm and claim upto 12% increase in economy.
