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,

I have to say that when I read of others who have had problems with my kind of set up, due to "other" shops, I count my blessings that I was referred to you. The car is a blast to drive. I have also noticed that HP is definitely a drug. Now I want more, but I also realize that I have reached the safety limit of the lower end. I couldn't be more pleased with all the work and the incredible tuning you have done.
 
Thanks again Brad for the incredible work you all did.

I will always thank the team at RPM for the mainteance and service of my Ford F250. And also the high performance work on my Shelby GT500. I will continue to use RPM for all my auto needs.

Thanks again,

Thanks to the Team at RPM for the great work to my 75 Corvette. The dyno tuning we did just brought my car up the standards that she should have had from day 1. Derivability, reliability, and my confidence in the way she runs has never been better.

Thanks again for all your help and great work!

Spoke with Brad initially on the phone for an appt. to get a new tune for my '02 Saleen. Upon arrival, Brad spent at least a 1/2 hour asking/answering every question possible about what is involved. There were several little quirks I didn't like about existing tune and said he could fix them. Returned a couple days later to find car running much better and fixed the annoying little issues with original tune. I now have a SCT 2X tuner with original tune, "bad gas" tune as well as back-up of existing tune.

Very professional and work done on schedule so recommend highly.

To anyone out there that wants their ride turned into a super ride, I brought my baby to RPM about three months ago, it was quite an experience, we have a service department, a machine shop--and a engine building room,-with one of the finest engine builders that i have ever met,-his name is Brian, then we have Marteen, he's a machinist by trade, he put a package together for me that was customized to my driving-this guy really knows engines--a 347 stroker, that absolutely rumbles,-we also have Don, the main man in the service dept...along with some of the finest mechanics that i have ever come across, I am so happy with this car, that it brings me back to the 50's,of course then, something like this would never have been possible,-the service is great,-the guys are like family, I've been treated like a king, the car is treated like a Rolls Royce,-would i do it again, -why, hell yes,-maybe in the next life time, when I'm younger and have more money,-way to go ,RPM,-honest as the day is long,-and they do the job, right--the first time,

While it took a little bit longer than I would have liked to arrange an appointment at RPM, once I got there, my experience was great. My 2006 Saleen supercharged Mustang GT had been noticeably less powerful over the last several months. Brad at RPM agreed to tune it for me. Since I live in San Jose, he was even helpful enough to allow a Saturday appointment, which was very convenient.

When I got to the shop he was very friendly and gave me a shop tour. You could tell that he cared a lot about his work and his customers' satisfaction. After a couple hours of tuning, he had managed to squeeze out another 40 horsepower for me and about 2 mpg better gas mileage.

He was honest and fair, and I'll be taking my car back in the future
