You gotta remember anything dealing with cars and their computers is expensive. Management software is just plain expensive. Here do this....call around to your various shops and ask how much a new computer for your car is. Next, ask how much it costs per hour to program/re-program your computer....You will find that $150 bucks is high or low in comparison to anything else engine management related. I want to see if I can get a hold of the AEM stuff.
