Hello everybody and seasons greetings im a newbie to the forum Need some help with low n75 duty readings. I have a stage 1 agu and its underboosting. It will boost to 0.8 bar and then slowly go up to 1-1.1 bar as rpm increases, no spike. When logging n75 it never goes above 76%, but this seems low for a mapped agu. It has a new maf, pressure tested with no leaks, and new n75 as it had an open circuit fault. Can anyone shed some light on this? Could it just be the map?
Thanks guys
