So you had the transmission fluid changed and an oil service?
Normally MB will not play around with the ECU unless you ask them or they had to update the transmission software. In this case they might have reset your ECU. Ask them and you will know.
Did the seller inform you about a tune? Unless you know or you have read the ECU it is difficult to say if there is a tune on a car.

I bought it from a dealer so they don't know the past history on it I will contact MB and ask the service advisor if they reset my ecu thanks guy for the help and tuning a stock car does that really do anything

It's possible that some transmission adaptations got reset when they pulled the transmission. It's the famous "battery disconnect reset." If the car had been driven very aggressively, the reset would tend to make the shifts more tame.
If that's the case, just drive it hard for a few days and it will relearn your driving style. Those shift adaptations can make a difference in the perception of power.

Adaptations are not updates. They're the transmission learning the driver's style. They can be lost if power is cut to the TCU. They'll come back. It's not a software change, just a normal result of disconnecting the battery.

at least in our TCU
and there are updates (TSB's, campaigns, whatever you want to call them) that perform an adaptation
eg, there were complaints about the 2-3 shift so if the customer complains about it the TSB says to run the adaptation routine for only that gear change
basically hook up the tool and erase/reset the old (only for the 2-3 shift)
drive the car at steady rpm, light load and shift 4 times 2-3 (some say 8 times)
park and let idle for > 10 minutes
there are settings for each upshift. each downshift and park to 1st and park to reverse iirc

Both the TCU and ECU have long-term adaptations and short-term adaptations. The former are stored in non-volatile memory while the latter are lost when power is disconnected for an extended period of time. The management computers apply short-term adaptations using long-term adaptations as a base. If the short-term adaptation gets large enough, it will be used to reset the long-term adaptation as the new baseline. Different management systems have different sets of adaptations, but the many, many people who report temporarily changed behaviors after a battery pull (either better or worse) are not crazy.

in response to a querey about adaptation

Clearing the trans adaptation requires a "HIGH END$$" scanner like AST, Baum, Autologic, Car-soft, or the dealer SDS.
None of the listed methods will clear the codes OR adaptations. (the listed methods were - scan tool clear, batt disconnect, tps reset (ignition key/accel pedal reset), and the HVAC head unit code clear methods)

That's talking about non-volatile (long-term) adaptations. A quick search will find dozens of people who have done resets of short-term adaptations with obvious results. I know I used to reset both my S65 and C55 often when my wife had "broken" them. The major adaptations can't be touched by anything but a DAS or equivalent, but there are plenty of short-term adaptations that have a noticeable impact on how the car behaves.
the short term stuff is reset everytime you restart the car and will adapt with style during a given trip based on throttle use, shift mode, l,oad, etc.

all represent mass hysteria?
Note that some of these include recommendations from MB techs to use the battery disconnect method rather than the accelerator pedal method, for instance.
