Help no boost
Hello all,
The other night it seemed as if my Agency Power exhaust seemed louder, anyway a day later when I went to romp on it the car did not take off as it should. No codes. My mechanic has looked over as many of the vacuum likes as he can get to. He pulled the under belly off and was able to see that the vacuum lines were still attached to the wastegate. He stared that the other wastegate was hard to see however he used a mirror to be able to see that the vacuum line was attached also. He said that the wastegate that he could see looked as if everything was fine with it. My 09 has 145k miles. It has a Jb4 with piggy back and the iPhone app. Burger intakes, oil catch can, down *****. Vsrf Charge pipe w/ HKS BOV, Alpina transmission flash, AA intercooler, Fuel it stage 2 LPFP, ST coilovers. Please advise what I should have him check next. My car has no issues & has always preformed as it should with all these fun mods. I put this same post on n54tech also. Thank you all for viewing this post. Thanks, b |

I've have had this problem before where my car would have 0 boost. the car had no codes and ran perfectly fine minus the no boost.
the first few 10-15 minutes of driving, my car was 100% full boost. but as soon as it warmed up and jb4 fully activates. the car all of a sudden gets loud and no boost, i couldn't access the jb4 steering wheel menu during that time, but when the car was cold i was able to access the jb4 menu. turned out the JB4 was the problem, got a new one and the car has been amazing. |

If you are the original JB4 owner, it will be covered under warranty (assuming that it is defective)
