Cut up to 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!

If you have a midcity engineering or other remote start, you must disconnect the unit before loading the tune. If not, it will create issues

All Mid-City Remote starters of any kind all come with a bypass plug to disconnect the system so our hht will work. It is the customer's responsibility to put in the bypass before tuning.

We will no longer take back or refund any hht’s because of not being able to tune if there is some kind of a remote starter installed.

Also if the customer bricks his ecu (not being able to start it) because of trying to tune without bypassing the remote start there is a $500.00 charge plus shipping cost to un-brick the ecu.

Description:

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!

Our Impressions:

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.

Availability:

We keep these in stock and ready to go! Ensure that you put your VIN number in the notes for faster tuning. Typically ships next day.
