Seems like all these tunes do is just turn the power button on all the time? Or just half way.....
How much more air/fuel ratio is possible than what BMW has given with the power button?
Is this just marking the engine run leaner?

ECU Tune gives you higher rev limit so you have more rpm which means more power + giving a nice air/fuel ratio tune to make the extra power more stable increasing graphics on the dyno..
"EDIT:Remember without deleting the cats ECU tune gives you 10-15hp. Going catless and tune and some other applications like lighter pullies etc. may give you 40-60hp. Look at M3 GT4. That's like stock engine with those modifications with other stuff."
You can also set up different settings on your ECU i.e if you using higher octane fuel or have exhaust valve system or something changeable...
There are brands that makes throttle sensitivity booster.. so basically BMW gave you one with only 1 setting in it.
Don't know much about DCT
