Hey gang, I was doing some surfing this morning and came across RENNtech, who does aftermarket performance mods for Mercedes and Chrysler. I was wondering if any of you have utilized RENNtech services before or heard about an SRT-6 owner who may have used these services? RENNtech purports to have a Performance Package for the Mercedes SLK32 AMG that includes a larger crankshaft pulley and ECU upgrade worth an additional 45 HP and 60 FP of Torque. The cost is $3,500.00...so you can make your own conclusions regarding the price vs the gains. Since the SRT-6 shares the same engine as the SLK32 AMG I was wondering if anyone has had this particular performance modification done to their SRT-6. It might even be possible that the ECU upgrade might find the 19 HP that the SRT-6 is missing in the first place too...but just guessing here.
