I just got a 2013 CM All4. I've read a ton of threads over the last few days and they are all starting to run together. On one thread someone mentioned a bolt-on tuning module other than the JB+.

I tried searching, but without enough information it's kind of fruitless. Anyone have any clue what I'm talking about?

 

Google Image search for the win, it was the SprintBooster.

 

The SprintBooster reduces the delay in electronic throttle response. The JB+ provides more engine horsepower and torque. Two completely different animals.

 

Yes, two very different upgrades. Some people even use both for maximum response and power.

The SprintBooster gets plugged inline with the throttle cable and basically shortens the response time from the time you press the pedal to the engine responding.

The JB+ gets plugged inline with the mass airflow sensor and basically intercepts signals going to the engine management system to up boost and net you more HP and torque.

 

Thanks
