To close this out, if it's not obvious by now Dinan went with a new manufacturer for the harness and chip, the V2. It feels like a more powerful tune, but still not without one small complaint. At 50% pedal there is a sudden drop in torque followed by a rapid onset of torque and the power climbs rapidly from there. It can be annoying when driving in comfort with cruise control set and going up a hill. The car just suddenly pulls hard unexpectedly instead of a more linear predictable acceleration. I spoke to the engineering department and they are going take a look at the issue once they finish a different project
