Cut 4 seconds off your 0-60!
On our shop 170wb 4x4 with 265/75-16 and full buildout, testing showed a 17.95 0-60 (via obd2 app) before the RENNtech tune
After the tune, we saw a 14.0 second flat.
This is the median of three runs total for each, throwing the fastest out, and the slowest out.
4 Seconds to get to the speed limit is a huge change!
Our proprietary ECU upgrade offers significant gains in both power and torque without sacrificing daily driver reliability. This maximizes the already capable Sprinter's ability to transport large cargo or tow large loads without degrading performance.
Tuning is available for Mercedes Sprinter, Freightliner, Dodge, and Airstream Vans equipped with the 3.0L V6 Diesel Engine.
RENNtech HHT (handheld tuner) allows you the unlimited ability to switch between tuned and stock ECU programming and requires no ECU removal!
The biggest change isn't speed. For us the largest benefit is the ability to safely merge with confidence with fast traffic, go up a long grade without losing speed while at 70 mph, and the ability to accelerate faster when you are in the 60-70mph range to pass someone.
We keep these in stock and ready to go! Ensure that you put your VIN number in the notes for faster tuning. Typically ships SAME DAY.

THE HAND-HELD TUNING MODULE / TUNE OR STOCK ON THE GO
The RENNtech Hand-Held Tuning Module creates significant gains in horsepower and torque across the vehicle’s entire powerband. By modifying ignition timing and throttle mapping, optimizing air-to-fuel ratios, increasing the engine’s rev limiter, and modifying boost mapping for turbo-charged vehicles, RENNtech performance software unleashes the true potential of your Mercedes.
