boost leak...or your DV just isn't holding....try tightening up your splitter 5 clicks or so and see what happens....

 

**** yeh! Look up the chart for vac lines... The one goin through the firewall thats going to the steering is a possibility. The check valve behind the engine. Intercooler could be leaking..

 

Oh yeh! You have a splitter I wanted the woooosh noise but was told from a couple people not to use it. Put the DV back in and see what it does

 

and you guys are sure its not my TB not being calibrated right from my battery dieing?

 

vacuum will be different depending on elevation. at 4500 ft i sit at 18-19 hg of vacuum but when i was in florida it was 20-21 so u probably dont have leaks depending on elevation.

 

^ pretty cool info

 

yea... ok in my driveway in neutral. its around 18, 19Hg... driving with my foot off the gas is around 20+Hg, can a bad n75 do this?, i bypassed it and hooked the turbo directly to its self. and was boosting 5psi.... so i was like wow ok... put the n75 back and it was back to 13 like before. so i cranked down my splitter and tried again... no difference... also by my intake there is a verry loud tick that would tick faster and faster over time when the engine is running. ill probly have to get under my car tomorrow and see if i got any bad vac lines... anyone got a diagram or a pdf of all vac/boost lines?

 

The ticking by the airbox is normal. I forget what the valve is called but there is that and also a check valve around that area that might tick. Scan for faults and do a throtle body alignment with vag com. You have that right?

 

i have the free version how do i do?

 

I'm still trying to solve my boost issue as well. I spike and hold about 10-11 psi and it's been like this since day one. At idle my vac is at ~20Hg right after start up and goes to ~25Hg after a little warm up. I haven't checked for codes since my vag-com cable has not arrived, but I did replace the hose that goes up away from the dv; it had a few cracks in it on both ends, but apparently that is not where the boost leak is. I also put my stock ecu back in (have an extra) to see if stock boost is lower than it should be, it's like it should be ~6-7psi and vac is ~26-27.
