Catalyst full service reqd

[Philly701]

I got an 2008 dodge ram 2500 4x4 6.7 diesel, when I bought it, it had 70,000 miles, now 106,000miles. I assume that it has EFI LIVE program on it, but no gages to tell what tune is on it,no way to contact previous, previous owner had done dpf , egr delete and now the overhead display is saying Catalyst Full Service Reqd, it dont have a cat on it, was wondering if EFI LIVE can help with this or if (then computer) just has this go on at 106,00 miles. Help please!!

Would need to be re-tuned.

Are you tuning it yourself? If not your best bet is to just google EFI Dodge tuning and buy a new tune, this forum is for tuners not end users, there is nothing you can do now except re tune it.

Also can try googling service required reset I believe you can reset that message it may or not come back though, someting like turn the key on and off 3 times then press the brake pedal or gas cant remember.
