SL65 Kleemann & Renntech Mods
Looking into getting one or the other and would like some feedback on owner's experience with their Mod. Please post before and after dyno results if you have as well. My tech informed me the increased cost of the 65 mod is due to an entire new TCU in addition to the ECU re-program. Anyway, curious of your thoughts on your performance gains and cost.
thnx all
