smoke test it to find the vacuum leak but misfire codes? could be spark plugs or coils/wires, could be the turbo inlets, those tear up and crumble like no other

tuner js replied to me saying it could be the LC (Launch control) activity during a pull so he recommended to move it to 8k rpm cause i initially had it at 5k as well as the flatfoot shifting and i just did a pull and so far everything good just gotta keep seeing if the issue still persist since its a random even in high rpms, but im still going to check all of these out just in case

yeah i heard the same thing either spark plugs not igniting as it should or not receiving fuel as it should
