Hopefully I'm posting right. I have a 2015 Eco, atm it has IC, Intake, catless dp, and axleback, the catless dp due to my inexperience with this platform causes the vehicle to run very rich and has already practically destroyed my plugs. I plan to get them replaced but need a tuning advisement as most big tuners wont tune catless now thanks to EPA scum. Can anyone give me any ideas? I also did try putting back in O2 sensor but no change. Vehicle is undrivable atm cause I don't want any damage. I am located in DFW, Texas.
