Cut up to 4 seconds off your 0-60! **The ECU upgrade is NOT compatible with the 2023 or 2024 Sprinters or AWD Sprinters** 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! This unit does not change the speed limiter. **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.

Due to the nature of installing a tune, any return or refunds would be at the sole discretion of Renntech. Returns on tunes are only accepted in situations where there is a problem that is unable to be resolved. *Note - If your van is equipped with remote start equipment, you may need to unplug that remote start equipment to properly load the tune. We recommend installing at home and not before a big trip so that if there are any issues with the installation you are not at a remote location.
