is it true that it takes more than 45 min. on a dyno to get a good tune?

As said before,it really matters on the combo and if the work done is right.It can take 15 minutes or 6 hours.The more the tuner has experience with certain setups will determine the time spent to get it right.There are also more than 1 way to tune a car right also.

You can never time a tune.Experience plays a big role.A typical bolt-on car would take me 10-15 minutes on the street followed by 2-3 dyno runs,before the drive I change a ton of tables for my starting point.Is it a bad tune because it was done so quick?No,it's called experience

I know that if I tuned cars for a living I would save all of the tunes that I did. And on a non tuned car I'd load a similar setup and go from there. Correct for the small bs, gears, tires, injectors and that should get you close. Take your time on the ground up tunes so you can use them later. Seems like common sense to me, its a business, its not UNICEF

I recently did a SC Vette. It was stock other than the SC. It just so happens that I did almost the exact same car 2 years ago. Both 2 bar SD, both stock exhaust manifolds, same injectors, everything. Same year cars too.
I plugged the older tune into the car I did recently, and on the first pull, the car made 525 hp, the fueling was pretty close, and it didn't set the 1514 code.
It took very little adjustment.
Does that mean that the tune sucked?

bolt on car 1 hour tops if its takin longer somethin is wrong or someone doens't know what their doin.
heavily modified cars with camshafts and blowers well them take a bit longer. some people bitch about how it starts how its idles and how long it takes to come down to idle after u start it. how it idles in drive. if someone has done many cars with big mods then they should be able to load tables fairly close to what they need to be but for someone just gettin started...may take the a while to figure it out. also modded cars may take some street driving as some conditions on the street may not occur on the dyno
