I have refrained from chiming in as I do not want to get into the dyno vs. road piece and the professionals vs. amateurs with Scott and Kevin. We disagree, end of discussion.

That said, I do not condone Ed's methods of high speed runs on the street.

I do agree however with a number of your thoughts on real road performance vs. the Dyno. Dynos are not magic. Repeatable, yes, realistic, well, who knows. Real race teams do both... Dyno, and real world tuning.

You can read all my opinions back in the coutless ECUtek vs. Accessport threads.

I still feel a day/week/month/lifetime of data logging and making small tweeks over time is probably the best way to tune a car. 3-5 pulls on a Dyno or 5-10 runs on an empty stretch of road cannot compare to 100s of street miles, 10s of autocross runs, and maybe 100s of track miles of test and tune at RFR...

Have a professional do your base maps on whatever system, and then if you want to go further, make sure the system you selected gives you that option.
