    I had my DTLT headers put on about a month ago.

    Since then, my exhaust has a much stronger fuel smell.

    Is it possible to make the engine run more rich due to less restriction?

    Or is it just because the front converters were removed?

    What would be the best solution for this?

    A/F Ratio calibrator or an MAF calibrator?

    Odds are, its because of the missing converters.

    lots
    more so because the converters are gone. if anything, the headers probably leaned it out a little.

    Yea, I just talked to a friend that is an engine tech. He said that it's the lack of converters.

    Do you think there is anything I can do, or should I just live with it?

    these trucks run rich from factory. only one i've seen that has changed his fuel/air is TacoSupreme over at TTORA. he used a scanguage or one of those other fancy computer programmer do-dads. i know mine runs rich, because of the scum that builds up on my rear quarter above the exhaust...tough as hell to get off.
