    I've had FTRA/whisper lid on my car for years and never threw any codes. Double check everything and make sure you don't have any leaks, IAT is connected, etc. What code is it throwing? Don't know about the jet chip making a difference. If everything else is OK I'd contact fasttoys and see what they say.

    171 and 174 at the same time means you're lean on both banks - most common cause is a vacuum leak or a PCV issue. See what gearchatter.com says for those codes for your year.

    ~110! According to gearchatter diagnosis chart could be a fuel problem also. Assumed it was throwing them only under normal driving conditions. Maybe you hit the rev/speed limiter or something? Don't know what they are on the 3.8

    I think the Jet chip is more likely the culprit than the FTRA...
