I got my dyno chart and this was done a while back. Thought Id leave this here for you as promised.

Nice gains.

I have had a couple of cars with piggyback tunes. It might lead to low boost being logged, but that is just circumstantial. The whole point is that the computer is being fooled to think the target boost is not being hit and allowing the wastegates to remain closed longer. I have taken off the piggybacks before going to the dealer for regular service. They never noted anything. Then again if there is catastrophic powertrain damage, they put everything under the microscope.

I have a Rebellion piggyback tune which is similar and I have a bypass(stock settings)that I plug in when I take my car to the dealer and haven't had any issues with them finding anything. These piggyback tunes are great for guys like me that worry about warranty issues associated with ecm tunes that would have to be removed (ecm sent back to tuner, tune removed, ecm sent back to you and installed, then to dealer) before taken to the dealer. I am curious to see how much(max) power can be made from a piggyback in the future since it is relatively new practice for these cars.

Thanks for posting a dyno graph... it makes you look much more credible, but I'd like to see those same gains on a 2014+ (AWD) model. Your original claim was you can get extra power out of the 2015s because they have different ECUs, and as far as I've been told, the RWD cars can make more torque with a tune than the AWD models because of the torque limiter in the ECU of the AWD models.
