Has anyone had to take their truck in for service after using the spartan? I hear that they are supposed to be undetectable if you take them off and re-install the dpf. Any truth to that?
ford can detect if the truck has been tuned one way at the dealer and its when the last regen was and if u put the filter back on and regen then bring it in ur fine ford tech guys can go deeper and find out how many regens u have had since u the truck was new thats how u can get screwed but ur truck has to be all messed up for a tech to come out from ford so put ur dpf back on and run it for a while to get regen then ur all goodSeveral people including myself have had their trucks in for service after using spartan and have heard nothing from Ford about it. I would not be nasty to them if you bring it in after using it. If you p_ss them off then they will look for a reason to screw you. I also used a SCT and took it back and they didn't say anything. But they did make me take the AFE off and put the stock intake back on before they would work on it. Now if you blow your motor then they might dig deeper. But no problems so far that I have heard of.
