2012 cruze eco 6 speed
BNR tuned; i was getting up to 22psi and the boost would slowly drop to 15psi, emailed and was advised to get their wastegate and recirculating blow-off valve.
uploaded the tune and installed parts, went for a run and pressure never gets past 14, i then went to the "yellow" spring in the blow-off, no change
i go back to stock parts and previous tune, boost stays at 15.
i ordered the springkit from forge and put in the "blue" wastegate spring, now boost goes up to 16.
next i replaced the wastegate actuator -ACDelco 55574902- no change in boost.
pressure tested and it held 20psi for about a minute and slowly got down to about 5psi, it kept 5 for about 5 minutes
im going to pull the downpipe and check the turbo wastegate this weekend. any ideas for me to check before i open a ticket with BNR?
