After checking online, I came across RPM Dyno Tuning in Rohnert Park. I spoke to Brad regarding my particular wants, and set up an appointment to get my 05 GTO performance tuned. Brad asked me what I wanted to achieve, and then he set up the car accordingly.

The initial results were fantastic! Brad had me drive the car for a few days, and then fine tuned it based on my request. I must say, the car drives amazing! Not just faster; the shift points are firm and well timed based on my driving habits. Power is right were it’s needed.

It was money well spent, and I know it was done right!

Thank you Brad and the staff at RPM,
