Hi, I wondering if anyone has remapped a 2019 145hp petrol Mazda 6? Bought one for my wife - it is a lovely car but let down badly with the gutless engine. Various remapping companies claim an extra 30hp.

Just wondering is it worth it?

 

I have seen these claims. They may work. I honestly don’t know. I have usually considered this a form of snake oil. Hopefully, someone of here has the answer and can confirm if there is a benefit.

 

Sorry, Mazda mapped your engine extremely well; anybody who tells their remap can get even 5 hp out of the engine is lying to you; 30 hp is akin to saying, "Hey buddy, I've got a bridge to sell you."
