It's says it gives you free tunes for life. How noticeable are the hp gains? If you had or have one on your foxbody share what you know about it. I'm thinking of getting from american muscle but I gotta ask my fellow stang enthusiasts to see if it's worth it or not.

Unless you have significant mods on a Fox Body engine, a chip is a waste of time and money IMO. They won't do anything for you that your ECU and you can do yourself.
Just keep it tuned up good and save for those mods.
Like previously mentioned the HCI mod will really give your HP a kick the the @55, then you'll have something to tune for too.
I would not be myself if I didn't mention that I consider chips to be a waste of time and money for our cars in most cases anyways.
Note: This is just my opinion and I'm sure lots of people will disagree with me and say that my preferred choice of the AFM PMS & a wideband is to expensive. If you think about it though and start adding up the costs of the chip, dyno tuning and reburning the chip every time you want to make changes, then you can see that my preference begins to make sense.
Don't get me wrong about the dyno tuning. It can be very helpful in eking out the maximum HP, but they also do that in a semi controlled environment and once you leave that environment and the temperature and humidity changes your tune will be off a bit. Therefore I believe that tuning with the PMS and a wideband can be more beneficial because you can adjust your tune "on the fly" so to speak.
