mrh, where have you seen anyone running 1.4 or 1.5 bar on a 996tt motor? I am running 1.3 bar, but I am also running an adaptive boost controller. It has two buttons for two boosts. I use 1.1 and 1.3. They can be engauged at any time. I wouldn't want to be running 1.3 all the time. Longevity would not be very good.
