Sorry about not being able to fit you in on short notice. I dislocated and fractured my shoulder in a skiing accident and couldn't work for about a month. Its finally healing up and I'm back up and running now.

As far as road tuning versus dyno tuning, I believe its possible to get good results from both assuming a good tuner and necessary equipment. I do believe, however, that any dyno tune should at least get logged and verified under real conditions on the road. Most dyno tuners around the country will start the tune on the dyno and then fine tune on the road. Sadly around the bay area none of the dyno facilities are in areas that would easily allow any logging or tuning on any roads nearby. Given the choice to work on a tune only on the dyno or only on the road, I would almost always choose to do it only on the road to make sure the tune is appropriate for real driving conditions and the customer's driving habits.

FYI, I do offer dyno tuning using the DynoDynamics chassis dyno at Speed Element for those who feel uncomfortable with road tuning. Note, however, that there is no appropriate place to perform any road tuning at this location. While its more convenient for me to use this dyno facility, road tuning is still my personal choice for the overall end result.

Some of the features of dyno tuning:
Benefits:
- Convenience
- Controlled environment
- High resolution power measurement

Drawbacks:
- Simulated environment
- Unrealistic airflow over radiator, intercooler, intake
- Sometimes unrealistic load curves applied to the wheels
- Lack of ability to test and tune quick transitions such as on sharp throttle movements and quick shifting.

Some of the features of road tuning:
Benefits:
- Real airflow over radiator, intercooler, and intake (no over heating short ram intakes)
- Ability to test and tune for quick shifting and throttle transitions
- Ability to tune overall drivability to accommodate the customer's driving style and habits.
- Much more involved and educational experience for the customer

Drawbacks:
- Very few appropriate and safe places to perform road tuning, which usually involves a longer drive to get to the road tuning site than it might to a dyno facility
- Small risks associated with driving the car in a spirited manner in a straight line.


BTW, I will be contacting some of the small airports around the area shortly to inquire about renting out space for road tuning. Aside from a private test track, I think that would be the ideal road tuning location.

Thanks
