Hello -
I'm new to HP Tuners and wanted to ask those more knowledgeable than I to take a look at my tune. I'm happy with my local tuner, but am looking to learn and understand more about my car and the tune specifically. The car is a 2009 G8 GT, stock motor, mild cam. At stop lights it occasionally shakes a bit and I've had to up the idle to around 750 to help reduce it as much as possible. Additionally, when cold, there seems to be very little vacuum as the brakes require a large amount of effort to engage. Finally, I'm seeing ~15mpg combined now where as I was seeing 20ish before the cam.
To be completely clear, I'm happy with the car, I would just like to learn more about the car such as why I'm seeing such poor mileage and am getting the shakes. If anyone could review my log and tune I'd love to start learning!
Thanks
