I have underexposed TMX 100 (120) by 2 stops. I normally process this film for 8 minutes with liquid TMAX developer. How much time should I subtract to process this film?

If you have underexposed the film, you will need to increase your development time, not reduce it. There should be instructions on the T-Max developer bottle, but a quick glance at Kodak's site tells me that they recommend 9 minutes at 75 degrees for T-Max 100 at EI 400. The info is here: http://www.kodak.com/global/en/professional/support/techPubs/j86/j86.s html#005a
