On my daily, it's just a usual stage 1 equivalent tune, FMIC and usual supporting mods, no dump pipe.
I have the seat sport FMIC on both of my polo's and still get heat soak when on the track, but takes at least few laps on warm days. You can't replicate that driving style on the street. I have/am considering changing the FMIC on the track car, but won't be anytime soon.
