I've seen this also cause idle stability problems when tuners raise MBT such that it no longer matches the engines physical characteristic.
If the MBT number no longer matches the engines actual MBT, then I suppose you could fix it by making the torque tables inaccurate as well. I would just rather both be as accurate as possible and not just one error offsetting another.
