2 step harming car?
I wanted to just simply know if using the 2 step, but NOT actually launching, hurts the car in anyway. I just like hearing it, but if it puts excessive wear on the engine, I'd rather just save it for when I actually launch. All I could find on other threads is the wear caused if you actually launch it as well.

you should be fine ive never heard of a failure from 2step.. if you just rev it up and let it hit a couple times and let off I don't see any harm. just wouldn't advise holding it there for extended periods of time.
Well it can depend on the two step and how it's tuned. Factory revlimit at a stand-still is basically harmless and all it does it build like 1psi. The only thing I could think of would be exhaust piping and its gaskets being damaged. Correct me if I'm wrong
If you log your car, check and make sure you are not knocking bad while doing so. And as essej stated it depends on your tune. If your timing is highly retarded and lots of fuel added "aka popping flames" you could have a high knock count and that would not be good, even thought there isn't a load with the knock.
yes, you definitely can hurt the engine with 2 step. I have seen engine failures during 2-step (building boost). It's a **** load of stress on the internals/bearings and has to lead to premature wear on damn near every component.
if you really feel like being an ******* in parking lots, just set a low stationary rev limiter

Incorrect. When I had my 9 on e85. I played with the timing and fuel and was making anywhere from 4-6lbs of boost while using the stationary rev limiter.

Anti-lag is completely different than a simple 2step rev limiter. I wouldn’t do it all the time just for fun but i wouldn’t worry about it being bad for anything.
Anti-lag in most cases is for turbos larger than say a 35R where a simple rev limit wont spool it. Anti-lag is a system that retards ignition timing and dumps fuel so you get spark while the exhaust valve is open creating a really hot charge going into the turbo. This will spool a turbo up really fast. Anti-lag is also used in between shifts (not on everything) when you shift it will do the same process as above to keep the turbo spooled for the next gear. this happens in between up/down shifts and de-acceleration. You mostly see the latter on WRC and serious race cars. Anti-lag is hard on turbos cause of the extreme heat but will hold up to it as long as you don’t overdo it or do it wrong. You really don’t need antilag unless you’re running a LARGE turbo on a 4g63 but if i ran something like a GT35R or bigger i would use it.
Rally anti-lag is a entire different thing and is called the "real anti-lag" by most people.

Can really mess stuff up if not tuned properly. Back in my subaru days I wrecked my original stock motor playing around with launch control and flat foot shifting using Cobbs accessport
