I have had a Haltech and Tec11 on a Pantera. The Haltech is very easy
and can be programed in a few hours. The Tec is harder to program, but
once you get it right, it is very streetable plus you also have ignition
timing along with fuel control. I would go with the Tec unit if I had a
choice. I have a heavy modified engine, with a large cam and the car is
mostly street driven and idles at 950rpm with very good low end and
great top end. The car was just chassis dynoed and had 
451 rear horsepower with the potentional for another 50rwhp but the
clutch started to slip.
