I felt it more zippy and less sluggish from 0MPH to 30MPH. This feeling was immediate after installation. It is also zippier through out. It is claimed to aid in gas mileage, but I have never measured before or after as I only had about 1100 without it and 200 with it. Plus, I didn't buy the thing for its gas mileage (even though we'd all love to have 1000mpg -LOL). I noticed it also doesn't have the speed limiter. This is helpful here on the occasion.
On Friday I had the CASE relearn done. You will felt no change before or after this is done. It was a 5 minute job from a garage with a Tech II scan tool. You only need this if you get the core exchange. The other 2 buying options it will already be done for you; therefore, I might recommend these. The thing with the core exchange is that you only have to do the install once. With the other options it will be twice.
Install is quick and easy. I have the habit of breaking plastic tabs in the cold, cold weather. Just take your time (and do it in your warm garage). The install was about 5 minutes starting, 5 minutes of labor, then 30 minutes to do the security relearn. The latter isn't apparently always needed, but you will know it is. It is really easy also. It just has steps where you need to do this and that and wait between steps. If you have no fear in changing your own oil then you should have no problems. Some people have recommended moving the fluid reservoir for more access room. I think they are smoking wacky weed as it would make the installation longer, more complicated, and really isn't necessary.
I was looking in Performance Products catalog last night. There seems to be loads of these "tuning computers" to mess with performance. This, however, was available now for the H3, was fairly inexpensive, and I am happy with the benefits. (LOL- would be nicer I guess if GM shipped it initially with one.)
