Default Predator question

I downloaded the performance tune on 01 coupe. I was looking for greater response on shifts. I previously owned a Pontiac GTA and
installed hypertech and was able to chirp wheels when floored it?

increase the shifting pressure to +10, and decrease the shifting speed -10.

Attempted to make changes to predator tune. After download was complete it gave me an error and then when attempted to start engine it was reduced power. I shut down immediately. Reinstalled stock tune and is fine. Anyone know whats up w/ Predator? Is it Predator. Thanks in advance

when using the Predator there must be no activity on the cars data bus. So you need to have the doors shut, radio off, do not raise/lower windows, do not select a memory seat function... etc.

all handheld tuners seem to be particular about this.
