When you do your test please be sure to post the datalogs so we can see the tunes are the same for each run.
I'm not the tuner, it is an email tune with no JLT and with JLT modification only :shrug:
I just showed 15+ RWHP over the stock box on our '13 no problem.
You ran it at the drag strip?
Or are you talking about a dyno again...
Don't you think you should address why you continue to claim 15+ hp and yet wbts testing showed ~5hp in the real world?
