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?
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.
