Getting annoyed now!!
Hopefully putting the cav on the rollers this sunday. So went out to try to set the boost up as its something i have never really got round to doing.
Running phase 1 chips, hybrid, uprated actuator, K&N panel filter.
The car didnt seem to over boost (expecting 17psi overboost - 14psi holding) held 14 adjusted it then it held 15psi, but seemed to pink/detonate so knocked it back down. Kept running it there and left it, went further up the motorway turn round. 4th gear 60mph booted it overboosted 22psi let off, booted agin 20 psi. Slowed down, tried again 14 psi as normal.
Any ideas?? it was holding 14psi ok but occasionally does this!!!flys up to around 20psi.
I have just replaced the hosing around the t-piece for the boost gauge ( plumbed in, in front of the ecu) havent tried it yet
Any thoughts at all ??
