Hello,
  1. I have a Audi S5 B8 Stage 1 from MTM and i Wonder if this is normal. When the car is about 44-46 km/h it shifts up to 5th gear for no reason this hallens when you use the speed up then hold it evenly you can feel how the car is jerking also you can see the revs going up and down but stops when you are up over 50km/h. The gearbox was recently serviced milage 11900km

Bad tune. Take it back. Was it a live map or ‘off the peg’ file.

Mine was done at MRC and no issues at all. It shouldn’t do as you describe.

Did you buy the car with the map already installed or have you recently had it mapped.
If it's the latter do as Andy says above. ,If the car had the map on before you bought it,get it scanned by see if there are any error codes.

I bought the car with the mods, i bought a injector cleaner and valve etc and solved the problems. I had the car checked on Audi they found nothing. The car is perfect now was on the highway to get the cleaner in the system and it did easy 290+ and still going
The Tune is from mtm With 2 boxes it just needed a clean and maybe some sparkplugs Will do the rest
