I have already added a few upgrades Lowering links, 20" HRE wheels, front & rear spoilers, tint, clear bra, color coded front grille, custom down pipes, Eurogharged heat exchanger and K&N filters. I originally had the Kleeman ECU/TCU tune but it threw a O2 code because of no cats. I didnlt want to take the ECU out and send it back to Kleeman, so I drove down to Eurocharged and had Jerry tune it. We dynoed it after cooling it for about a hour with the Kleeman tune. It made 549 rwh /640 rwt. After his tune it made 567 rwh 770 rwt. He also changed the shifting firmness and quickness. The car is a blast. I was actually looking at a SL65 black series yesterday but I don't think it's worth another $100k more as a daily driver...
