Well its if a factory ecu ,but not factory tuned ,look to be mines tuned one,
and would appear to have been untouched since.
ussally they have boost cut/R&R removed and speedlimter that sort of thing
and are tuned for mild mods , full exhausts ,pods, sometimes fuel, cooler etc.
but either way you are lucky ,you will have more midrange and better power over
stock ecu, and its already set for many mods, depending if you already have them.
have fun
