Performance wise, I plan to keep this car mostly stock (including the clutch lol). My main goal was to bump up the usable torque and soften the rev hang/boost delay between shifts. I "think" the TSP tune makes some additional changes to ignition/fueling in order to wring out some extra performance. As fun as it would have been, it was not the rabbit hole I wanted to go down long term.You need to get TSP Stage 1! It’s even more responsive than the KTuner base maps. I don’t think I can drive my car without TSP map 3 anymore! Fuel economy is definitely suffering but usually more when I’m in sports mode. Love my Si all over again! Can’t wait to do the full turbo back exhaust to gain even more power.
IMHO, the 21.5 PSI map is more than adequate on a daily. Though had I done a new unit, I would have definitely enjoyed sampling the TSP tune for a bit.
