Coolant Cap leak

Well here is the problem. I just installed a looney tune from Vivian, and when I WOT for a while I start to smell coolant. Now it is not a lot just sprinkles (wet around cap and on air intake hose). So could this be a faulty cap or is it something worse. I never had this happen till now.
EGR is deleted, CTS says oil and coolant temps are in rage of each other and the oil cooler and coolant have be changed (no more gold)
Also the coolant sits at the min mark.

Another note is that the coolant temp never gets higher then 188-190 goes back and forth. Could the thermostat not be working properly?

Thanks in advance!

Well the first time I did have it up to the max. Then I sucked it down to the min. But like I said it only just started to do this today. But I'll rig up a pressure test this week but I'm going to try a cap. I notice the cap from day one when I bought it it had a hump on the top instead of being flat. Idk if that was normal. If that makes any sense.
