Curious,
Where on the street are you able use 400hp for a sustained period of time? Imagine trying that with my 700hp 2,000lb hotrod.

Very Long stretches.

Honestly Once you hit the 11s it needs to be done on a dyno and finished by making sure you don’t have any drive ability problems on the street.

Most tuning for WOT is done in a single gear in a single pull. You don't need to pick a high gear. And yes, Dyno's are much more helpful when you make big horsepower.

I can see it for a heavy and low powered pickup, but not really possible to road tune higher performance machines. E.G. My bike needs 4th, (1-1 ratio) before wheelies are no longer a problem. Can't go over 1/4 throttle in 1st (ever), half throttle in 2nd (above 3,000) , or give full throttle in 3rd (above 5,000). I expect you couldn't explore much of the powerband with a supercharged or turbo 5.0 and stay out of jail.
Sorry, just can't see tuning on the street being worth the risks on anything with some power.

If you can afford all that power you can afford the dyno time also

There's also... you know, THE TRACK where you can TEST and ... what's it called? TUNE?

Street tune just means street condition...

Discrediting how useful tuning on the street is because some vehicles are really fast doesn't make any sense. 90% of tuning on the street is making it act right way below 100% throttle, cold starts, idle, shift strategies, etc.

I've been on a number of different dynos, but my absolute favorite was a Superflow SF-849

Shift strategies is a good point. Have to admit that I have never once tuned an automatic trans vehicle. Always been manual.

Our shop uses a Mustang dyno. However, the Mustang dyno numbers are usually lower than other brands. So if the largest number is what you're after you need to go elsewhere.

They were able to get a safe 40 horsepower and 50 lbs/ft. out of my 2001 GT, and that's really impressive for a tired 2-valve mod motor.
