HELP!!! engine noise under WOT
Hey guys, I am getting an engine pinging noise at WOT around 5250 to 6000 RPM range. This noise also happens when cursing around 75-80 MPH and start to accelerating in fifth gear. This problem really started around the time I had put the headers on and, right now I am babying it because I cannot afford any major engine problems. So, any help you guys could lend would be greatly appreciated I am a little worried if I have to take it to the dealer. My Mustang is a ’07 with JBA Shorty headers, a K&N FIPK intake, and a Diablo Predator with the K&N FIPK tune installed.

Are you getting a CEL? If you added the headers after the tune, then you may need new tunes but you may be ok because of the shorties. But the K&N FIPK tune, IMO, isn't anywhere near as good a tune as you can get. I'd contact Bama for some new tunes and then go from there.

Or, you could have gotten some bad gas.

The solution is to put prothane motor mounts on.
If that's not it, you can take your predator and pull 2 degrees of timing from 4000-7000 rpms. Then you can half a degree at a time.
I did not need a retune with the JBA's.
