THOR #12698
Mercedes Benz Sprinter Horsepower/torque upgrade

I decided to go forward with modifying my 2018 Thor Siesta 24SS which is built on a 2017 Mercedes Benz 3500 Sprinter chassis. I am going with OE Tuning in Santa Ana California. I went by their shop today and set up an appointment to have my sprinter's ecu modified. They claim the ecu modification with increase the horsepower between 50 to 60 horsepower and increase the torque 70 to 80 Tq. The features of the tune will be the following:

Ignition boost fuel mass adjustment
Torque limits and boost limits are raised
Increased fuel economy
Speed limiter removal
Improved performance, throttle response and drivability
RPM and shifting limits can also be increased

The smog is unaffected and no required emissions components are removed. If the dealer removes the program, a free re-flash is included. The original factory settings are saved and can be reinstalled if needed.
