It's just surprising the the vendor wouldn't let their customers know that important detail.
Those box tunes aren't what I would call the most refined tunes on the market. Do they offer custom tuning? You may look into something like that to take it a step further. That may get the result you're looking for. I know Ray @Double R Diesel does customs tuning for the RaceME. I just don't know if he does so when the product was purchased elsewhere.
