You do understand I do this for a living right? I have literally tuned thousands of trucks in all configurations you can possibly think of. I recommend things that work. I have never had issues with AMS downpipes because as per FORD OEM logic, they are considered efficient.For the sake of clarification on this story im only replying one last time bec you keep insisting on saying its the cats which is misinformation. Ive mentioned all there is to detail the problem and those who understand how this works knows cats doesnt shut off the obd2 o2 and cat monitors. Any faulty cat will cause the monitors to complete with a fault code. Yours never recognized that.
For the record the only reason ams downpipes pass is with any tune or stock file because they are 300 cell cats which are above the cat efficiency threshold which is based off the temps variance between pre o2 readings and rear o2 lambdas. Even nick of optics can verify this.
Whats even more infuriating about this issue is even if i did go ams i bet my life the tune you gave me still would have the same issue again bec i know the monitors on the tune you sent is disabled. Its not as if the tune knows the cat is efficient or inefficient so it doesnt go ready, unless thats the algorithm set which means it's your tune thats tampered with emissions. What youre not getting is I wanted those cat monitor failed codes so i could resolve it independently but yours did not. At least admit thats where you and i are not seeing things clearly.
Your downpipes are not efficient and throw P0420 and P0430. Note!!! At this point, I can no longer help you. My tuning does not alter/modify/bypass/change (insert synonyms here) emissions devices in any way. I do not have control to set monitors related to emissions, codes related to emissions, etc. I think that is where you are confused… I cannot make any changes whatsoever at all as the COBB software I use does not even allow it.
The reason you are having the problem you’re having is because you chose inefficient cats= P0420 and P0430. Your truck is telling you this, I’m telling you this, COBB told you this and smog told you this. I do not know what else to say. If you’re only complaint about my product was me not disabling those codes for you as you specifically asked for, I did my job. Your job was to get quality downpipes like I told you.
If you want to call me please do. Otherwise, stop mentioning this in public at the same time you’re mentioning your tuner as you’re going to hurt them in ways you clearly don’t understand.
Like I said, give me a call and we can discuss this. Otherwise please stop talking about this. You got your “fix”. You can now move on and be happy.
