cutout/stumble on an MC engine

[Rob]

If it is an un-modified turbo, your ECU will cut off the fuel pump at 1.6
bar. Use your trip computer as a guide. See if you are going over 1.6 bar. I
modified my wastegate to give myself more boost but haven't modified my ECU
yet and I get the same cut out if I accelerate really hard.
