HELP!! ticking after tune

[QuinnXcii]

So last weekend, i got my tune. (half tune) aka just license since they couldn’t tune it at that moment and time and this morning, i started the Z.. heard clicking noises coming just from my driver side header, when i rev/accelerate i can hear it as well. same spot. any insight? i’m new to this stuff so i’m lost in the sauce.. would appreciate all that help i can get.. couple things i researched, what it could be.. oil (changed that today) since i thought it was that. nope, still ticking. then i looked it up and saw it could be the valves, rod, pistons, so i’m lost in the sauce.
