I think it's a horsepower threshold error. The ECU probably has a limit and once it reaches the limit it throws the code. Remapping allows the threshold to be set higher. Either that or I'm talking out of my ass but it seems about right. But luckily these DT malfunctions never put the car in limp mode. At least for me. And it [usually] only happens when you decide it's time to drive the car like you stole it. At least for me, lol. Once you restart the car it just resets itself so it's not a big deal.
I have catless down pipes, resonator delete, and BMS tune. I had it happen 1 time when it was stock. And 2 times In a row with all those mods. So 3 times total.
