I have a problem with the ECU not recognizing full boost for about 500rpm (3000-3500) before it registers and then starts to pull timing out. This led to pinging (excessive timing) was fine at time of tune but couple months after, discovered the issue and lucky nothing gave way considering it pinged but only Audible through headphones on dyno. Have since had timing adjusted, but that's the strange thing safety setting was setup to retard up to 4 degrees but it didn't. Anyone know if map sensor is faulty or nock sensor. Would like to fix this b4 retuning.

The Wastegate Solenoid is located under the fuse box... The Boost Sensor is on the aluminium piping in front of the battery, should have a resistance of 4-8ohms.. if that helps.
