So it’s been about a day or two when I noticed I started lacking in boost pressure. It does not go up to 6psi when before it was almost at 14psi what could cause this problem?
Simplest answer: bad gas. More complicated: leak in the downpipe causing a lack of pressure to spin the turbo. Also possible: Bad o2 sensor, defective wastegate Go to iWSTi.com and see if they have any ideas
