hey i just got my car all done and brought it 3 hours away to my college and tonight i was driving and opened it up in 1st gear and then shifted into second and shifted normally. well then after that i looked at my boost guage and my vaccum is sitting at 0 and my idle fuel pressure is at 48psi instead of 28psi. I then turned around and brought the car back to my apartment. does anyone have any ideas what it could be? Its dark out now and i dont have a garage or a flash light at my apartment so i could only see with my phone.
help me out please
i do have a turbo xs manual boost controller on a hahn stage 2 kit
vac line would be my guess... but that may only make sense to me seeing as your having vac problems, start small lol
good luck

yea.........vacuum lines..........the one going tot he guage, perhaps split off to the fpr?
zip tie all vacuum lines to fittings...saves the day
As said above, you likely popped off a vacuum line, melted a vacuum line, or one of your charge pipes popped off. Sitting at 0vac at idle might explain the increase in fuel pressure.

well they all said it 0 on a vac gauge means atmospheric which would be a vac hose or a charge pipe disconnected(which would feel a lot less power) check all your vac lines and zip tie them to the fittings. thats about it its all said there!

you guys are missing a huge point his fuelpressure doubled at idle.
I almost guarntee its the small hose that comes off the top of the manifold and goes to the fpr
if your fpr sees atmo, then your going to have full fuel pressure, and your going to have a vacum leak which brings the manifol to 0 vac

Actualy if the manifold is at 0"hg then he will have a lot more of a problem than a small vac leak. For the manifold to have 0"hg then it would be a huge leak and the engine would be bouncing off the revlimiter. This is presuming his vac reading was at idle, as the origional post was not exactly clear.
Now if the car runs fairly normal and the gauge reads 0" hg then something is probably wrong with the signal line to the gauge.
unless of course he T'd hes bost guage off of the same vac source that his fpr is on. but that would be to obivous for question
