As far from JBS as possible !
Nope when in limp mode the ECU restricts engine power as limp mode is a safety feature programmed into the ECU to stop engine damage. Car could have gone into limp mode for many stupid reasons but MAF is unlikely to be one of them. Usual reason is the turbo over boosted slightly for some reason. Most of the time after switching the ignition on/off the car will drive like normal and not go into limp mode again.
