had one on an old deutz 180.7. worked really well for a couple of seasons of heavy draft work, but then I started noticing some funny noises when changing powershifts pulling a subsoiler. after that I turned the chip off and swapped the tractor at the end of the season. I think it didn't help the 180.7 was the biggest model in the range at that time using that backend, if I was going to chip another tractor I would do it on a model low-mid in the range.
Good point. I wouldn't chip the MF7618 or 7718 [current model] much, because they are the highest power tractors with that transaxle already.
MF6612 should be fine with a bit of a rise in power and torque but do check which model and power of tractor is the first with the heavier duty axles and don't exceed their power output.
Personally, if long term reliability was top priority, I would buy the horsepower needed and if it was a mid-power tractor for that chassis, I would have the flexibility to chip/map it a bit in future should unforeseen circumstances call for more power.
