So, Basically, i had a set of KO4's put on my 2.7t and had it mapped with boost set to 1.4 bar..... a year later and the turbos failed, got them replaced under warranty but now with new turbos on i only hit around 1 - 1.1 bar with a bit of a spike to 1.2-1.3 in 6th gear only but then settles back to 1.1, never drops off or anything like that, so dont think iv got any leaks, could it be the actuators pre-load is set differently? or would this not make any difference due to boost be controlled via N75?
