from searching around, technically it will run fine on a stg1, but to get the most from it, a stg2 setup would be better, taking into account the mods you have
as most of the mods you have already point to a stg2 setup...as in a way its a bit pointless sticking with a stg1 map with all the mods you have as it is not bringing out their full potential and in essense the potential of the car and power as a whole
