Oh, Aidan is a competitive vendor? Now his statements make sense. LOL!

The JBD retails for $279 and the customer can install/remove in seconds without visiting a tuner shop. The difference vs. stock is really night and day. What do you charge for your flash tuning? And how much time does the customer have to sit around while you upload and download maps on the car? And then for warranty work to go back to stock again? I do flash tuning as well and it can work quite well when done right. But it is a much more expensive option in the case of the X5D/335D. And in general has advantages and drawbacks vs. piggyback tuning.

Here are a couple videos of our JB4 gasoline piggyback system which retails for $529. Can your flash tuning do any of this?





Any a dyno charts on pump gas vs. stock tuning...
