smy 60 tc mini not reaching temp with kanger ni200 in subtank mini

[actripsix]

setup..
smy 60 tc mini
kanger subtank mini v2
kanger ni200 .15 occ coil head v2/vertical
batteries ranging from lg he4, lg hb6, xtar vtc4, sony vtc5's

i had been vaping with the original kanger ni200 horizontal coil head with no problem. then i changed to the new vertical version of the kanger ni200 which was fine for a couple of days, then all of a sudden the mod wont reach temp anything over 450 or so, i like vaping it maxed out at 600 .. anyways, i did some research and couldnt find much in the way of not reaching temp, mostly people having problems with reaching temp too fast, read about pushing up the 510 connection before installing the occ head and so forth.. thought it may just be a dud coil head so i changed to a brand new head even though the one i replaced was only 2-3 days old and was working just fine until today :S popped in the new head and still the problem persists THEN i tried doing some of the things i had read, such as pushing up the 510 connection, poking the cotton from the side of the coil/juice holes, fiddling with the spring loaded connection in the mod, checking to see if any method worked between each interval... no dice! can anyone help? thanks in advance

Moved to Temperature Control to see if you can get help

Don't know much about your mod, but does the vape feel cooler than it did on the old coils? In other words was 600F on the old coil hotter than you're getting now at 450F? If not, then this means something is funky with the resistance reading (with TC, it's all about the mod being able to read an accurate COLD resistance).

What does this coil read at room temperature as far as resistance?

all of the coils in this pack are reading between .17 and .19, though they should be .15.. The vape is cooler no matter how the temp is reading.
