Speedriven’s advanced ECU software tuning turns an otherwise stock Mercedes 4.7 liter Biturbo V8 into a serious performer, packing more than 535 HP and 600 TQ (SL550) without compromising the cars’ refined nature. In the blistering heat of summer, though, that serious performance engine is going to generate some serious heat. But don’t worry: Speedriven has the answer with its “Stay Cool” Biturbo Performance PKG.

Throughout the summer, Speedriven is bundling its ECU software tuning with an intercooler pump upgrade and a set of high-flow drop in filters for a special price. Just $2000 … and that includes next day return service for your ECU!


- ECU software upgrade (regular price $2000)
- high-flow drop-in filters (regular price $~100)
