I have tried both EFI Live and Autotap and both lose connection around half throttle. I Have tried 3 different computers now and various settings but so far the only thing I have been able to use successfully is a Tech2 scanner. Never had this problem on F-Bodies using the same software and computers so I know it has to be something with the car.

I have with the VCM Scan from HP Tuners no problems.

I have noticed no problems so far with EFILive, other than some of the PIDs aren't "there", because Paul Blackmore hasn't gotten ahold of a GTO ECM yet. I'll have to try jumping on it, to see if I experience the same problem. A new update was just released, so I'll download it and give it a whirl.
