Jesse,
sounds like you've got a too rich situation; you should have no hesitancy when blipping the throttle. IIRC, the Dobeck website tells of a procedure to tune the TFI and checking for hesitancy on accellertion by blipping... IIRC, it's for setting the second pot (yellow).
My experience was that the TDM didn't need much if any more fuel by the yellow pot. So it should be set to 2 o'clock or less.
The TDM benefits most from fuel added by the first pot (green) and you should find the ideal somewhere between 2-4. 2 is recommended for stock pipes and filter and 4 would be too rich for almost any bolt-on mods. I found my tune at just a shade under 3 IIRC.
The 3rd and 4th pots deal with wide open throttle and very high RPM running... not somewhere most TDMs would spend a lot of time.
Jesse, my recommendation to you, is to set the 2nd (yellow) and 3rd (red) pots fully anti-clockwise (their zero or off point) and set the 4th pot fully clockwise (its full RPM position). Making these settings will turn off all TFI function except for the 1st green pot; you need to get this one setting correct first as this is your base air/fuel ratio (AFR).
Get your AFR correct and you probably wont need any of the other settings, but they are there if you want to tweak them (later) for more/better performance.
Try this and let us know how you go.
EDIT:
your stalling in the shed, definitely sounds like too much fuel from the second pot (yellow); it acts like an accelerator pump.
