I had a generic Hypertech chip a long time ago and to be honest, it was a huge waste of money. Now that was 5 years ago and maybe they have gotten better through the years but I would say don't waste your money.
A friend of mine had a custom tuned chip in his almost stock 95GT and it just ran circles around mine. He bought the car used and didn't know what kind of chip it was. So I went out and got gears, pullies, o/r h-pipe, cat-back, and the generic Hypertech. His pullies, tb, stock 3.08 gears, and custom chip car pulled harder through all the gears and was just plain faster. That chip maximzed his air-fuel ratios for max performance, did away with the tip-in timing retard, turned his fan on earlier, and did away with the 2 second delay when going to wot (at least this is what I assume it did since it was a custom design and that's normally what they do).
Again, maybe the Hypertechs do that now but I don't know. If it's still the same old program, I would say save your money and spend it on something worthwhile. Just my two cents
