OK....I have to leave for work in a few. I searched and searched looking for the answer, but when I search "boost" i get every post that says "Ecoboost" in it.
Here's my question.
I loaded the Unleashed "Performance + Firm Shift + Boost" tune. I turned on the x4 to monitor boost PSI. After a couple of WOT runs, the max boost showed 15.08. Is this OK/Normal?
