Ok, ive been having a problem with idle and boosting lately and ive finally fixed it..
The dump valves!
So ive removed them and refitted the recircs, but im still getting problems when on boost, at high rpm's i hear a sound from the exhaust that sounds like its dumping oil or fuel and it's struggling to get to the redline. EDIT - Missfiring!
It also feels down on power and the boost gauge is stating 0.6bar (8.7psi) when running on 1.2mm boost jets which should be 0.8bar (11.6psi)
Ive search everywhere for a boost leak but cannot find one or hear any hissing anywhere.
Ive also done a ECU error code check and o2 sensor check and all is fine.
All injectors are firing and all the connections are in good nick
All coilpacks seem to be working and all connections are in good nick
