RENNtech just sent us details of their tuned version of the SL65 AMG Black Series, which takes the already consummate model and boosts output to… wait for it… 805 horsepower. That’s 5 horsepower more than the BRABUS, allowing those in the RENNtech camp to sit smugly back and gloat in the fact that their tuning package is clearly superior to their competitors. Making the magic happen is RENNtech’s SL65 Black Series Performance Package 1, which includes ECU/TCU tuning, a dual intercooler pump upgrade and sport mufflers. Pricing starts at $16,390, while a RENNtech transmission upgrade and limited slip differential are optional extras to compliment the newfound power at your disposal.

dual intercooler pump upgrade... like on the slr. I dunno if the BS comes stock with two pumps, but in all cases, that must be a serious upgrade if coupled with bigger intercoolers and bigger HE.
