Should I get my bike tuned?

• Most bikes don't require remap, reflash, or tuners like Power Commander, however, we do recommend it for some European bikes like 2019-on BMW S1000RR and Ducati V4. More details are available in the description of each model.
  
  

How's the HP gain is measured? 

• We have our own dyno and we always use the same bike, settings, fuel and temperature conditions to provide reliable results. All number are achieved without tuning the ECU
  
  

Will I get the same HP gains described?

• You may get better results and here's why. All tests are made in Brazil where the gasoline contains 25-27% of ethanol. Ethanol has less energy efficiency than gasoline. The energy content in ethanol is 33% lower than in gasoline. This means that the engine power will be lowered when the ethanol content goes up. 
  
  

Why do I hear pops and bangs from the exhaust?

• The engine backfire on deceleration is also caused by the too lean air/fuel ratio - A lot of people think that the backfire/popping in the exhaust is caused by too rich mixture, but it's actually the other way round. They're harmeless to the engine though.
