Installed H&S Xrt pro and MBRP Competition Series DPF-Delete dual exhaust friday night .Drove the truck aggressively and the check air filter came on across the odometer screen . Installed Afe stage 2 cold air Saturday night retuned the truck ,cleared codes and still have the Check air filter message !!! What Now ???
I love all the mods, truck sounds like an animal and is incredibly fast on wild setting ,afraid to run hot setting because I can't keep my foot out of it
until I do the egr delete and maybe head studs.
