The problems you are having don't seem like a temp adjust (calibration) problem. You have said the device gets quite warm. My guess is you are having an issue with the device getting a good seal on the stem or other air flow problem. That can be hard one to diagnose. If it were working properly you would not be confused about whether or not it was working, I think. I seem to remember a similar issue that turned out to be the internal thin oring that sits above the glass being missing, tho if you haven't had it apart I'm not sure why that would be the case.
Round up
. It’s also been stated herein many times that glass varies. My stock TM short stems do, both outer and inner diameters - and I haven’t measured them. I can tell the way they fit into the stem holder without adjusting it, also the way some CU orings fit well and some don’t and the CU tends to slide more easily within one stem than the other. Glass is class but can be a pain in the ass - sometimes. 
@Misterhyde86 You're probably already aware that there is a 5-7 second heat up period that ends with a slight haptic vibration. If you're starting your draw before that and pulling significantly, you may be cooling the chamber faster than it can heat to proper temp.
I think cybrguy is right and you may be missing an oring that is causing sealing issues, though it still seems odd that your ABV would be getting dark. But I haven't heard of anyone getting your results from a properly functioning device, so maybe it is defective in some way (again, most complaints along the lines of what you're experiencing involve a lack of sealing at some point).
I appreciate you both and everyone else that tried to help me. I have to admit I probably came across pretty pissy in some of my posts. I explained my situation in email to the manufacturer, he responded within a few hours. He was apologetic and said that it didn't sound like my device was functioning properly. He didn't give me any steps to follow, he said he would send me a new unit to try. I guess its possible I got a dud. I thought I could get darker ABV than I could as well, I blasted it on 10 earlier for a good 20-30 seconds and got light brown ABV with green still.
) as much as we love ours...
No worries here -- it's not a cheap product and I can see it being very frustrating to have so many people saying how great it is when it doesn't even work for you. I'm glad they're sending you a new unit. I use it on level 6 exclusively, through the stock stem and GRAV upline tasters, and that leaves my ABV pretty dark (besides the green ring along the glass).
Ditto. And I’m no longer using the nuts & washers in the cooling units. Love me my TM!
I gotta try hai ku!
my hits at 10 are typically a bit shorter than when I'm down low. good way to play with the high setting is with the wpa and a bong while using on demand mode, hit the bong and as soon as thin vapour starts let go of the button but keep hitting, it will thicken up before stoping later, can crush .1 in 2 hits with avb the colour of a almond skin
but the simplicity of a stem on its own is very nice for when I someday take my TM out and about!
I can’t say I’ve ever tried on 1 and starting at 4 always works for me with my style (10 second gentle draws), getting nice taste the first couple of draws and perhaps a third for one session (another 2-3 draws between 5-6 to finish things off). Decent clouds throughout and AVB consistently a medium brown. I could go darker meaning using a higher temp but I’m good. It’s routine at this point - and it’s awesome! I’ll try it on 1 but I can’t imagine getting any vapor that low. Everyone is different though (see above) - all good!I get visible vapour at 1 and top out at 10 if I'm so inclined
