O2s

Alright guys, im running shorty headers, catless h pipe, gt500 mufflers..i ran into an issue where my o2s weren't ready with o2 spacers...so i drove it up to 400 miles stop and go..still not ready...i removed the 2 o2 spacers and ive put 300 stop and go miles on it but the o2s still are reading "not ready"and they haven't thrown a code....any guidance would be helpful..

Are they turned on in your tune? You need to get with your tuner on this.

Guidance=take the car to a good tuner. Or get a legit remote tune. That means a LEGIT tune, not bama or some other "tunes for life" crap.

They are only a pain in the butt for a tuner who sucks. You can also just run a good catted pipe... its not like it'll cost you any power.

Also... "upload and try"? The car should be tuned properly while on the dyno.

Hes a few hours away and we do datalogs..but the car has been tuned for over 2 years...i just finally needed to get a brake tag. Tuner is great and i hit him up after hours of research and he sent me a revision..so ima see if it works when the weather gets better

You need to put the cats back on

If there are no cat's and they are shut off, its never going to show ready for read.
You defeated an emission component, it won't present like that.
Put the cats back on and get the tuner to turn everything back on.
