#4924, "Boost Problems.."


          

Well finally got my new car running with the new oil line but my boost will cut out. not all the time just sometimes?? its weird. i start it up in the morning drive it around fine boosting 10lbs. then go home turn it off and then go out alittle while later and drive it and it cuts at 6lbs. this is on my autometer boost guage not stock guage. it does this constantly! one time it will be fine the entire time driving until i turn it off and when i turn it back on its fucked up! theres no boost leak that i found. i did my own test

What kind of controller is it

Also try doing a vacuum leak test and a boost leak test. Maybe when the car is at operating temp. something isn't tight or zip tied and is expanding causing a little leak.
