Hey guys, I just got a 2007 335i.
Want to get some extra power, and modify my car.

After I read some topics, it sounds the Juice Box is the way that the most people go. But I heard from someone that he said Juice Box might make your car overheat. (I don't know if it is true) He think Dinan is the best way to gain extra power. So, what do you guys think?

And Juice Box Stage 3 states it can gain 80hp on the wheels, anyone is using it and know if it is true?

Thank you very much!

Short answer is no, the JB3 will not make your car "overheat" in a situation where the Dinan tune would not.

But in all honesty, it sounds like you need to do a lot more research before you buy anything. There is a lot of information on what the difference is between each tune, as well as how tunes work in general. Read up and make an informed decision. There information is already out there.
