RENNtech SPEEDSHIFT Valve Body Upgrade w/ Throttle “Blip”

Thursday, April 24th, 2014

The staple of advanced or professional driving is the “rev match”, or “throttle blip”, in which the driver quickly brings the engine up to speed with the wheels by use of the throttle. This was not possible with the automatic transmission in the CLK Black Series…until now.

RENNtech is proud to offer our Speedshift performance valve body upgrade for the CLK black series. Our upgrade modifies the shifting performance characteristics of the transmission control unit, the transmission valve body and allows the vehicle to automatically “blip” the accelerator upon down shifts allowing for quicker gear engagement and faster lap times.

When downshifting, the engine throttle is increased to allow the engine to match the RPM of the lower gear and allows for significantly faster gear engagement . When coupled with our transmission upgrade, this is the ultimate upgrade for your CLK Black series.

Tesla S vs RENNtech tune only E63

Wednesday, February 6th, 2013


Published: Feb 05, 2013

The same Tesla Model S that successfully beat a Dodge Viper in a quarter-mile showdown is back this week going up against a Mercedes E63 AMG.

Instant torque is a wonderful thing yet EVs in general are not popular amongst gearheads and probably never will be. That doesn’t distract from the fact the new Tesla Model S is quite the performance machine. For last week’s installment of Drag Race Tuesdays we saw the Model S successfully beat the Dodge Viper SRT10 on a quarter mile strip. As a result, it set a new record as the world’s fastest production EV.
Now that same Model S is back, this time going up against a RENNtech-tuned Mercedes-Benz E63 AMG. So can the mighty EV repeat its incredible performance from last week? Check out this week’s quarter-mile showdown to find out.
