O2 Gone bad again!

[rbswan384]

Hey guys, I am stumped on why my 05 Gt keeps burning up my bank 1 sensor 1 O2 sensor. I purchased the car used. The guy who originally owned it put a mac cold air intake, full length headers, removed the cats and put mac exhaust. I've added the assistance of an SCT tuner and have the rear O2s off. The only thing that is not programmed to the car is the cold air kit. I really do not want to put cats on the car if I dont have to. Does anyone have any advice?
Thanks

When you say you have the SCT tuner, is it just the handheld or do you have a custom tune from a reputable tuner? I would get a good mail order tune for the mods in the car and maybe check or replace the injectors in the side that's giving you the issues.

Hey thanks, its just a handheld. The plan is to go with a roush charger so the injectors will be replaced then.
