    1998...whats up with this year???

    I have read through the forums on here and found out a couple of differences. My buddy said that the headbolts were weak on the 98 and 99's but i'm kinda skeptical. Another thing is the pcm, is the 98's pcm not tuned as accurately as the other years or just different programming. And lastly, whats up with the blue tinted mirrors???

    '98 uses a different pcm than '99-02. And the blue mirrors are on some '99s too - a friend has them.

    It's Not the Head bolts it's the Rod bolts guys. This comes into play when large cams that extend the rpm range are used but if you keep it under 6500 rpm you should be OK.

    Some of the sensors are different too, ECT and oil pressure are a couple. And the temperature guage actually works.

    Edit: Thinking '98 was the last year for the Auburn diff, Torsens started in '99.

    My 98 had the auburn diff. IMO I loved the blue tinted mirrors. Driving at night people's headlights don't blind you from the reflection. +1 for the temp gauge actually working. First mod I do for my new truck will be the aeroforce gauge so I can see coolant and trans temp.
