well first off on my boost controller your spossed to screw it in for more boost and out for less. mine is the opposite screwed all the way in itll spike to 15 the drop to 12-10. I unscrewed it to about half way out and now it spikes to 20 and drops to 13-15. dont know whats up with that. second, how do i find a leak in my boost pipe/ intercooler setup??? im figurin it has a leak because of teh boost spiking the falling down and its a high pitch wistle. oh yea its pingin a lil bit at 15 psi how do i make it stop?? mess with timing?? what causes pingin exactly ?? i dunno just wonderin
Are you sure your boost controller isnt hooked up backwards? The bottom should be Source vac, side should go to the turbo. As for Pressure testing...check out this thread on turboford. It tells you how to make a pressure tester. http://www.turboford.org/ubb/ultimatebb.php?ubb=get_topic;f=2;t=036993 Dr.
