when it was set up originally with my old turbo but still with air injectors they turned the boost up to fine tune it by using the actuator. it now has a chip to run the new turbo... when i rang last week for some info was told it should run 30psi and probably had an air leak .. ive checked and am sure their is not.. ill get on the phone tomorrow .... as soon as it starts making boost it flies straight to 25 and stays their.. if not ill just leave it as it is..
