no, it wont go away with a mail order PCM. they leave a lot of the traction control and abuse mode stuff alone. you need someone to sit in your passenger side and change what you want them to change.
when i was tuning i was knocking pretty much purely from the car trying to pull timing because i was making too much power. i had to keep raising the thresholds on everything until finally it would let me make the power without trying to pull timing on me for making like 300 ft/lbs of torque or more.
