Title: no boost with wastegate pipe off
Post by: turbotoaster on September 22, 2010, 12:15:39 AM

                                                   hey guys, ive converted it over to non-seq yesterday, having a few  problems as my boost controller doesnt seem to do anything.

anyway, i disconnected the pipe off the wastegate actuator just to see  if there was a problem elsewhere and i got loads of boost...15psi+

today ive tried again to get the boost controller to work and failed.

so i took the pipe off the wastegate actuator again and now it only hits 6-7psi of boost.

checked underneath to see if the pipe had come off the flapper but thats still on there.

so im a bit stuck.


what could cause only 6-7psi on a non-seq when the wastegate actuator is recieving no positive pressure at all.

i checked the boost pipes for leaks and they are fine, could my BOVs just be dumping all the boost?
