My 04 GT pings under heavy load above 70 mph in hot weather with the a/c running. I resort to using the midgrade fuel (89 octane) instead of the regular unleaded (87 octane).

Since I'm forced to pay for the 89 octane, would I be able to advance the timing a little using a timing adjuster? Enough to benefit from it?

The more you advance the timing the more succeptable to pinging. Mine is set to 15 degrees (via EEC reflash) and I have no trouble with 93 octane. The timing advance seems to give a little more low-end grunt.

Does everyone with a timing adjuster run 91+ octane?

It could be the good ole K&N oil on the MAF wire problem too. You may want to clean it.

With a timing adjustor you have to run AT LEAST 91 octane, 93 is even better. If you dont then you will get pinging. Ford recomends NOT cleaning the MAF sensor.

I have to run 91 octane? Can't you adjust it just far enough to get the most advance without pinging with 89 octane?

Just run the 91/93 and eliminate the pinging all together. The car will run better. If your gonna run a timing adjuster and bump the timing up past stock, your gonna have to run 91/93.

It's better to be safe and run the 93, You don't want the motor to knock under WOT and you might not hear it. If you want to mod you car, you can't pinch pennies when it come to gas.

I told Tim that I wouldn't quote the exact price on SN but it is cheaper than a chip or a timing adjuster plus a few other things. For example, you can adjust for gears or turn off your post-cats sensor, tweak the A/F and have the computer re-learn new mods and maintain the "good" settings.

PM CobraKiller. Tell him mrvax sent ya.
