No, not really. There is a lot of debate about whether or not those PROMs or chips really add HP or not (it doesn't matter the brand, Hypertech, Jet, Motorvation, etc.), but the general consensus on these boards is that they are worthless. I have to agree, because I own a Hypertech chip for my car, and it did nothing, absolutely nothing, it just sits in my toolbox now.
Now, there is power to be gaining by burning custom PROMs, but not with those generic chips. Just check the DIY PROM board, and read the stickies at the top of the page. It only cost about $150 to get the equipment you need to burn your own PROMs (not including a laptop).
Hope this helps.
