No real times as of yet. Haven't had chance to make it to the 1/4 mile track since tune was installed. (it's 2.5 hours away)

Fuel consumption has not decreased under normal driving conditions, if anything I've noticed my fuel consumption increase. I think a lot of it has to do with breakin of the engine. Everything else about the JB3 has been great. My only complaint is that it can throw shadow codes (too much pressure in the wastegate mainly) however it seems like the JB4 will take care of that once it's been tested on the F25s.

I still recommend the tune regardless, it makes the driving experience that much more... its exactly where the F25 should be. I've turned off the tune the last 2 weeks just to see if i noticed any difference, and once you've experienced the JB3, it'll be hard to go back to stock. For how much it costs, its worth every penny.
