JB3 Chip Questions on 07' 335i coupe?

[NYZ93]

So i wanted to know a couple of things first about these chips...
- is a JB3 the best value for the power it puts out??
- any mechanical problems after installation?
- is there any other add ons needed with JB3? Oil cooler? Upgrade Exhaust?etc
cause the 335 already runs on high temps.
Thanks.

The JB3 is probably the best value increasing the bhp. I have seen most of the cars that are taken to the track with it go into limp mode. If you don't take your's to the track you seem to be fine, even here in hot American south. I have the larger Dinan intercooler,oil cooler, and increased water pump speed and my car still got up to 280 degrees oil temp last month at Road Atlanta. It was a 30 minute session and we had a lovely heat index of 114....
