Alright, continued problems.
I'm getting very low vacuum, this is my first problem. Its hard to tell, but in my video my vacuum is reading around -10/-11.. When I give the car gas, the throttle response is real laggy and boggy and when the car goes into boost, or tires to, it starts to spit, sputter and backfire a little bit. Then when it does get into boost, it seems to rev up fine (But slow), but then continues on to overboost.. The car idles fine and as you can see, I'm getting normal wideband numbers.. If you notice though, when I let off after noticing I was overboosting, my vacuum fell to about -20 to where it should be, but then slowly goes back to -10/-11....
Really confused on this one.
Do I have a massive boost leak somewhere? Is my wastegate stuck closed, or open, or stuck in general? There is a vacuum line capped off on my wastegate, should this be connected to something? Am I getting fuel cut from overboost, even though I'm allowed to boost if I play with the throttle? My IAC valve is not fully hooked up, just the air line from the intake to the IAC, should the coolant lines be hooked up as well? Is my low vacuum issue causing all of my problems?
All testing was done while the car was in neutral and just sitting in my garage. I can only apply small amounts of throttle to get the car to rev up and continue to rev.. Anymore then like, 15% throttle, and the car bogs down..
