It won't run bad, it just prevents the check engine lights from being thrown. You'll mainly want to disable P0420.

I reflashed today, last night I was doing a 3rd gear pull and it felt like traction control was kicking in but it wasn’t .. it was weird ?

what catless dp did you put on? Do you feel any gain? Did the cel come on right after install or it took some driving to come on??
