any way to advance timing on a 4.6 withouth timing adjuster or chip??

put a 100K ohm resistor in your IAT sensor connector. it tells the pcm it's like 29*F outside and advances your timing about 3 deg. cost is like 99 cents at radio shack! I eventually bought a steeda unit and got the best results at 5 deg. adv. 15 deg. base timing. fyi.
