Dreamer, I have the Tec III going on an engine now. No feed back to offer yet. Went with it so I could eliminate the distributor on a BBF. Have a autocross car using the rotary engine. On it I have the SDS unit. These guys are good and they specialize in SB Fords. Unit is small and VERY simple (simple digital system) and does not use a computer. Comes with its own "meter" for tuning. The units are preset for certain engine combos and the user can only alter the fuel map a certain amount above or below the factory setting. Keeps from burning pistons, etc. Support is excelent, but not really needed. They now offer a full distributorless setup. Would not hesitate to go that route after my experience. Web site is
