Try a colder spark plug too....

TPS on a 93 GT should be at .98 - .99 volts...with key in ignition and throttle closed.

RE: Some Pinging at High RPM

So you think I should chip it then? I was holding off on geting a chip as I wanted to get a custom dyno tuned once I was done with all of my mods. I dont have an adjustable fuel pressure regulator, but that was soon on my list, so it may come sooner.
Also, someone suggested that 1degree cooler of a plug might fix it as well? How do plugs work in that sense?
