The car in question is my Renault 5 raider, the boost is currently set at 14psi using a bleed valve, i am planning on taking the car on track next month and was going to up the boost a little and get the fuelling checked /set up before hand, i was going to remove the bleed valve and adjust the boost at the actuator, just want to know if there is a correct procedure to follow or weather to adjust a little and try until at the desired level. Also is there anything i should be aware of or looking out for when doing, or should i not bother and just adjust using bleed valve that is already fitted?
