    Only mods he has are a K&N air filter which I have told him to ditch (in addition to cleaning his maf sensor)

    What do you guys think is up with the knock? I'm concerned about the Fine Knock near redline. Should he switch to a LWG map? I don't think that changes anything except the wastegate duty cycle right? He just went to go get a new airfilter and some maf cleaner. Hoping that fixes the issue. Also this was a 4th gear pull.

    Good call on ditching the K&N and cleaning the MAF.

    How many miles are on the car? Has he owned it since new? What behavior made him do a data log i.e. was he having some soft of problem?

    Just over 60k on the motor. Reason we did a datalog is he just flashed to a stage 1 map. He is the 2nd owner, looks like the motor was never touched.
