If you want to run a bar you need to ajust it to 1.10 mate should have said I'd have done it the other day I've got a evc4. there is 3 setting aswell alt will switch between 2 hi and low. there is also a 3rd setting mate sbc is another one that you set to say 1.2bar from anything from 5sec to 30sec and when you press it will go to the set boost for the set time
