I bought the eds ipf that allows you to remap at home. It comes with maps for stages 1-3 and a few options each stage.
I recently got 223bhp and 282ft/lb from a stage 1 high torque map
I also have a full turbo back exhaust system, de-restricted airbox, panel filter and hard boost pipe with collins dumpvalve.
Since then i've added a fmic and been running stage 2 but not been on the rollers with it yet.
MPG do eds software and they are probably the closest to you.
