does he have any mods done, does he have gauges. what does he have that isn't stock. with some mods and pulling hard my first guess would be a SES light due to over boosting.

That was my guess. Does the light go off after acouple of starts after the hard pulling or does it need reset manualy?

My 02 does the same thing when pulling a hill.
It always goes out after awhile.
I have a Edge in mine.
Ive always thought it was something to do with the Edge but there wasnt anything I could do about it so I just ignore it .

Whats "overboosting" and what can you do about it?

Out trucks are set to start defeling at about 24lbs of boost, if your computor sees more than that it will sense an overboost situation and start cutting the fuel to bring down the boost. Usually in a hard pulling high throttle setting when this happens, usually will set the ses light, throw a code, but after a number of starts if the computor does not sense this anymore it will turn the light off.
