You really need a dyno to tune correctly.

you can work on the street, and that is great for drivability, but going WOT on public roads, is not safe.

I don't like doing heavy throttle 2/3 transmission calibration on the street, since it is hard to find a place to do this kind of testing, safely/legally.

Tuning on a dyno is the safe way, tuning on the street is the dangerous way. I prefer to use a combination of both.

You can tune on the street without pegging 4th. Unless you use a true load dyno, the tune will be off when the car gets on the street unless you know how to compensate for it... A "Dyno tune" does not cover the drivability of it. 98% of dyno tunes just bring the WOT AFR in line and thats it.

That is true.I've proved it many times.Do a full load dyno tune then hit the street's and high speed runs were way off from the dyno.I guess this is why people pay proffesionals to go fast
