for a naturally atmo engine 7age{not fe} is good but for superchargeing i would just put a gze with one of john's nevo pulley kits on! the cost etc just isnt worth it. even for an nat atmo engine it will cost a bit unless you do the work etc. the fe head js not very good for anything but saving fuel. just swap a gze with standard computer and nevo kit and smile.
