Most good tuners will have a time frame of about 5 minutes which is very impressive.
Other could take from 6 to 10 minutes which is not a bad thing. However, ensure that the tuner does not take too much time during the ECM download. The data you will be handling also make a difference, so you need to consider that.
Versatility
When choosing a tuner, versatility means how well the tuner can adjust to the performance capacity. If the adjustment is good, then you can make changes very easily. It also gives you a scope for experimentation without much trouble.
If you follow a different driving style, this would be a great opportunity for you to try new things.
Even though this is not a major consideration, you could treat it as an additional feature. If your tuner provides features that make it versatile, you will have an amazing product at your disposal.
