They say that good things always come back around. From Scottsdale to North Carolina, and back to the Valley of the sun, one of our existing clients was fortunate to find this very special RENNTech SL55 up for sale. Originally Dyno-Comp built this SL55 AMG back in 2007 for Ray Durham of the San Francisco Giants. It was featured in the Modified Luxury and Exotics Magazine Jan 2007 Breaking 500. With a bit more Dyno tuning we were able to achieve 510 Wheel HP and 540 wheel TQ which equates to a whopping 637hp and 675 tq at the flywheel...and there are plans for more!!!!
