Likely you have modded stock injectors (which is what DW produces). If you had unmodified stock injectors, the car would run very poorly on a map designed for those DW 565 injectors. Since you have a lot of unknowns with this car, I would take it to an experienced Subaru tuning shop and have them do a once-over on the car. The only off-the-shelf (OTS) map we have for DW 565 injectors is the stage 3 map which requires a VF39 turbo, stock or Cobb SF intake, and, obviously, those exact injectors. A front mount intercooler is going to be outside the scope of the map.
