I have a Hana DNA30 clone and I am loving it but haven't pushed it past 13W yet I think I want to try 1-1.5 ohm build next what Guage wire should I use on what size drill bit and how many wraps?

OK, that explains why you were getting a decent vape! Unless you're swapping with a mech, dropping the resistance doesn't really help you with the DNA30. It actually can restrict you since it has a minimum voltage which varies a bit. It's spec'd at 4 volts but if your battery is lower than 4.2 it'll drop lower. I'd personally recommend trying a 2.0 Ohm coil first, because it's my favorite. It also works well with a DNA30 because the resistance is high enough to allow you a nice range. A 2 Ohm coil will hit 4.0 volts at 8 Watts. That's 12 wraps of 28 gauge Kanthal a1 on a 2.4 mm form (you'll find that a lot in precision screwdrivers as a slotted size).
Now, to answer your question, a 1.5 Ohm coil will hit 4 volts at 10.66667 Watts. If you go below that on a fresh battery, the DNA30 will become a very expensive mech. It just dumps the battery direct without trying to modify the output. Not to say it's a bad thing since I've enjoyed those coils, you just have to adjust the DNA30 down as you vape. So, you start at 10.7 Watts and then adjust it downward as the battery depletes. It'll flash at you if the Wattage you're requesting is too low. So, you should be able to hit that with about 8 wraps of 28 gauge Kanthal on a 2.4 mm form.
I'll leave the 1.0 Ohm alone for the moment, since I would suggest trying the 1.5 first.
