[QUOTE="theACE, post: 13512506, member: 117925"] Am I going to be same with a Steeda tune on a ZFK0 2012 5.0 with only mods being MRT 3" Hi-Flow Performance Boss H-Pipe, Airaid CAI, Flowmaster Outlaw AB's, and resonator deletes? I am at 20k on the clock with 5k full synthetic oil changes and a Moroso air/oil separator. I always run Shell 93 gas, from decent looking stations. I am scared because I have read Shaun from AED posting that the only thing that saves these motors is when they detect detonation and go into "save the cats" mode. With a mid-pipe turning off O2 sensors would remove this "save the cats" feature of the tune wouldn't it? I know Steeda has never had a #8....but I am worried. Especially since I have read on here that ZFK0 is a really failure prone ECU/PCM. I understand that #8 can happen stock, however since I currently have a CEL for cat ineffeciency, I have been told to throw a tune on the car that will remove that and improve performance....and AED posted that they have developed a fix to get around the #8 issue. Only thing that is odd about my car is that when I turn it on, for about the first 5 seconds if I rev the motor it will make a lope type sound and gurgle. This ALWAYS goes away after the first 5 or so seconds of operation, so I just wanted to make sure it was okay. My idle is about 750 to 1k once warm, but it is a liquid idle...it moves up and down from 750 to 1k. Please ease my emotions, I don't know much about all this motor stuff but I am trying to learn and understand it all. [/QUOTE]
