I found my high rpm/high boost miss. It was a faulty plug wire. Installed new magnacore's and it runs smooth right on up the rpm band. That is ALL I did to this car today. Just replaced the plug wires.
On the drive to the shop, I could boost up to the 20 psi set in the cal. I let the cal control boost via the solenoid.
On the drive home, it only goes to 11 psi.
Got home, checked ALL vacuum lines. Good. Checked wastegate solenoid - not leaking past. Checked wiring connections as MAP, good. Checked temp sensor wiring, good.
Car is definitely going into open loop, so it is seeing WOT.
Disconnect vac line to wastegate actuator and it will boost up past 20.
No codes.
Under what conditions can the Blueberry limit boost? Part throttle. Cold engine. Anything else?
What else to look at?
