Coolant Leak?/Choppy Acceleration?

I have a 2018 Elantra Sport w/DCT and I noticed my coolant reservoir level went from max to min in about 3-4 months. I haven't noticed any fluid anywhere so kinda worried it might be a head gasket issue, although I haven't seen anything in the oil. Also noticing some choppy/jerky acceleration between 30-100% power. Anyone have similar issues and or solutions?

The jerky acceleration is probably the stock electronic boost controller which is crap and it's highly recommended to replace it.

As far as the coolant, there have been some instances of leaky turbo cooling lines. Might crawl under and check that. (might be able to see them from the left side of the engine bay) My suggestion would be to fill it back to max when the engine is cold and see if it goes down again.

Got ya...ya I live in Cali so as far as upgrades I'm screwed, basically everything's illegal here, but I'd have to look into it. I'll definitely take a look at those lines when I get a chance though. That acceleration issue is super annoying though

Nobody is going to know about the EBCS. It's a little black solenoid that is buried down in the engine bay. Just replaces the stock one.
