Problems with '08 6.4 and U7164 9r17

[dieselnoob]

I flashed the U7164 unit to the latest release (9r17) and the only mode that works is economy(50)/economy(50). When I select performance(80)/economy(50) or performance(80)/performance(80) the truck drives strangely. The best way to describe it is that the engine "lopes" - its as if the power is coming on, then off, then on, then off... over and over again, even though I have the throttle at a constant position. After setting it back to economy/economy it works fine again.

Any ideas out there?
