Zero regrets so far...just wish we could have avoided the whole HP Tuners fiasco.

Working with the factory systems, I agree with most of what you said. I would not run the factory computers in a race car.

I work with all the race systems too, and much prefer the FAST. It's also easier for customers to take over tuning their own cars after getting them going.
