I'd have to doubt it,especially with no way to prove it and also this bulliten came along time ago,and if this many colorados need it fixed they can't blame anything else,shit I had to get it done twice,sounds illegal.can a dealership really make that call and void the warrenty?
I don't think he's saying it fucks shit up,just that the dealership he works at is trying to blame the head issues on the cat deleteAbsolutely no way the manifold cat mod affects the MAP sensor or 2nd O2 sensor. Rear O2 readings are solid 750mV before and after for my truck. Zach, report what yours reads for us. Anyone else with the tuner can do the same.
Common sense question: How are all your trucks running out there? (those with cat mod) Any CELs? Any problems directly associated with manifold cat mod?
Listen folks, I have a full manifold sitting in my basement. Why, you ask?? So, when I tested everything out and if by chance it did not work, I could return to normal. If it did not work (did long term testing before I made the write up), I would NOT have posted a write up.
I got nothing to lose or gain either way, it was just a write up but since I have the facts and data, let me speak...
Something tells me we are not getting the entire story. Who is this person anyways, anyone know this dude?
