Cat deletes? Please help!

Hey guys, I have a 2011 gt with gt500 axel backs and res deletes. I got the car used with that setup. And with a set of cat deletes, but I had him uninstall them so I could have it inspected for emissions. I'd like to put them back on. And he gave me the sct x3 tuner with the car. He has a 91 octane street tune. And 2 93 octane tunes on there. He definitely ran these tunes as he had no cats when I test drove it. I'm afraid the tunes will break the car. Do you think there safe. Being bama tunes? I also have a plx multi gauge. So I can see the timing and afr. What's normal timing, and what's dangerous timing for the coyote. Thanks.

Not safe because the cat delete tunes turn off the cat overheat feature that essentially dumps fuel to prevent the cats from overheating. Get new tunes.

Wouldn't the old tunes have the feature to shut that off. All three tunes on my tuner are made for a off-road exhaust

+1 he flashed it back to stock with the cats. More than likely the tunes are for no cats. Pop em off and load a tune.

Thanks guys. All three tunes are for no cats. I emailed bama. There's a 91 octane street, a 93 octane mild. And 93 octane race ghost cam idle
