I do my logging with DTC off, and don't see the reason why disabling DSC would make any difference on smooth highway straight line pulls. However, I did some logs today with fully disabled DTC+DSC and still get load overshoots with corresponding throttle closures (highway speeds).
The tune feels great otherwise, but it would be perfect without the boost spikes. I am currently attributing my timing pulls to the last 2 injectors that were not replaced with the recall. Those two cylinders are usually more noisy than the others.
