    - No difference in temp, the DV does seem to flutter. It now does hit close to 20, then drops off.. - blackfnTTruck 2017-07-29 20:30:19 (154 views)
  - Wait, maybe I have it backwards...100% is wastegate closed? - blackfnTTruck 2017-07-29 15:34:16 (158 views)
    - Yes 100% N75 DC is no airflow to the wastegate - at least that's what the ECU is requesting - Doooglasss 2017-07-31 12:03:02 (150 views)

    - With the DV relocation we have to reverse the DV valve too, right? Did you try it both ways? - Mr.Ramsey (Gr�nTT) 2017-07-29 12:20:23 (142 views)
      - You mean the stock one? Always have had it in the same way. - blackfnTTruck 2017-07-29 13:05:13 (150 views)

- UPDATE>>>car back, the tech did pinch off the line to the DV and the boost came back up. - blackfnTTruck 2017-07-28 09:54:07 (177 views)
  - What DV are you running? - TCU_TT 2017-07-29 18:24:26 (175 views)
    - It's a hyperboost, I think, I did clean and regrease, and did try my original stock DV - blackfnTTruck 2017-07-29 20:29:25 (144 views)
- UPDATE>>> looks like I'm on my own, they said since it's tuned, they can't fix it.. - blackfnTTruck 2017-07-27 12:02:53 (210 views)

    - That even looks like a lot of lag for a k04... shoot me an email. Your QW address doesn't work - Doooglasss 2017-07-27 12:44:20 (190 views)
      - Could we be ignoring a waste gate issue?   -  J. Patterson  2017-07-27 14:10:27 (180 views)
        
        Not ignoring it, anything is possible. I do have the Max spring mod on it, to help hold it...  -  blackfnTTruck  2017-07-27 17:40:21 (187 views)
        
        Could something in the wastegate be "in a bind", or rubbing/hitting something?   -  Gokart3  2017-07-28 11:57:10 (160 views)
        
        the WG would have to be in a bind OPEN to cause a low boost issue >  -  Doooglasss  2017-07-31 12:05:55 (137 views)
        
        I did do that and all works fine. Beginning to think I have an issue with the flapper seal.   -  blackfnTTruck  2017-07-31 14:19:47 (147 views)
        
        That is on my list to check, now that I have the car back. Although the dealer did pressure..  -  blackfnTTruck  2017-07-28 15:09:47 (170 views)

    - SAI is a separate system entirely > - Doooglasss 2017-07-26 10:28:04 (218 views)

        Yes...BEA...really appreciate all your help, they have it now, but have not figured it out yet....  -  blackfnTTruck  2017-07-26 12:04:51 (179 views)
        
        That red turbo discharge pipe can leak and be difficult to hear when pressure testing.  -  J. Patterson  2017-07-26 11:26:02 (200 views)
- So ever since you had said shop do the repairs, this has been happening? - VelveTTrevolvr 2017-07-25 15:40:22 (176 views)
  - It is with them right now, we'll see if they can find the issue, I have my doubts..... - blackfnTTruck 2017-07-25 16:54:53 (204 views)
    - Not far off -- the dipstick tube was a vacuum failure point on CIS VW's. Would throw off fueling - Doooglasss 2017-07-26 07:56:18 (168 views)
      - So it could be part of the boost issue?   -  blackfnTTruck  2017-07-26 08:02:16 (221 views)
        
        would only impact vacuum and I'm not even sure on newer cars it matters as much >  -  Doooglasss  2017-07-26 10:25:37 (197 views)
        
        My manifold has three of those clip on connectors, I thought one was not on far enough..   -  blackfnTTruck  2017-07-26 11:25:56 (199 views)
        
        Could your diverter valve be partly stuck open? >  -  gortt  2017-07-27 19:40:23 (159 views)
        
        I did replace the DV with my original stock one, bypassd the N75 with my MBC....  -  blackfnTTruck  2017-07-27 20:10:46 (181 views)
- Pressure test the hose between the N75 and waste gate...>> - RobertA3 2017-07-25 06:56:45 (211 views)
  - All the 100% duty cycle indicates is that the car is not getting to the requested boost > - Doooglasss 2017-07-31 12:07:05 (134 views)
  - But doesn't that hose help the spring to keep the wastegate CLOSED? ---- - J. Patterson 2017-07-25 11:27:09 (197 views)
    - Yup... - Modshack.info 2017-07-25 15:46:34 (200 views)
      - That does make sense...thanks guys. - blackfnTTruck 2017-07-25 16:55:38 (162 views)
