My XCalibrator arrived in the mail today and imediately flashed my 05 GT's computer.

It now feels different - I haven't had time to get a good feeling for it yet but it seems to have some more power.

I asked for a 91 octane tune.

I was driving in heavy traffic so I couln't really open it up.

 

How about the throttle lag? Did the XCalibrator resolve it?

 

Still seems a little laggy.

I have an automatic 05 GT, and it can be laggy as heck.

My previous car was a 94 GT manual stick so when I applied power, it was there.

With my automatic 05 GT, sometimes the power seems to go on a little vacatiion and then it finally kicks it after realizing I've floored the throttle pedal.
