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.
