After tune, tuner said I needed new o2 sensors
Just got a tune on my bolt-on only 99 T/A, and the tuner said that my o2's were bad and were dumping alot of fuel, causing my bad gas mileage. But if I had bad o2's wouldn't i get a check-engine light or anything? Occasionally I'll get a SES light but then will go off the next day.
The tune and dyno showed i had 331rwhp/342 rwtq. Any help is greatly appreciated. About to go on a roadtrip and I need the best mileage I can get!

Oh wow then I definitely need to change mine out, i bought the car 3 1/2 years ago with 79k miles and it now has 119k and I've never changed them! I'm not sure what codes were thrown but I'm pretty sure it was due to the !AIR and !EGR and no back o2 sensors since it was before the tune, but the light would only stay on a max of 1 day.
If they haven't been changed since factory then I'm buying two new ones tomorrow! They are usually around 80 bucks a piece right? Thanks for all the help! Gas mileage is horrible right now.
