Chiptuning

Hallihallo! Has one of you already had experience with chip tuning in the Ateca? I have ordered a 1.4 TSI with hand switch, i.e. 150 hp and 250 Nm. The chip, which I prefer is a Racechip Ultimate of 43 hp and 75 Nm provides. I worry less about the 43 hp, but rather about the 75 Nm, because I don’t know how much the gearbox (probably an MQ250) still has air up.
