Anyone use Hypertech handheld?

I have the opportunity to get a cheap unlocked hypertech 390202 handheld for my 1999 Suburban C2500 with the 7.4 liter engine thats almost entirely stock. I was wondering if its really any good and what tunes can it do? Does it have a economy tune for better MPG? Or should I just pay more for a better programmer?

I never saw better MPG with a Hypertech HPP3 on my 2000 5.3l Sierra, only increased shift points, rev limiter, tire size etc.
I'd opt for a tuned PCM over a handheld if you do not plan to play with the settings yourself.

I had a HPP3 on my 2000 C3500 5.7 and I could barely tell that it did anything. I couldn't notice any difference in the mileage aspect. I bought mine used for around $40 on ebay when I got it. But, now I have a custom tune from BlackBear and that Hypertech can't hold anything to the custom tune. The custom tune is cheaper than most new handhelds and it does a much greater improvement in power... and the mileage is a touch better as well. I got another pcm off of ebay for $20 and shipped that one out so that I wouldn't have any down time waiting for the pcm to get tuned.

I have one and it makes a hell of a difference in my 99 burban with 5.7 has 3 tunes economy, towing and performance and when I go to performance I feel the difference, the only thing is when you go above econ u have to run 91+ octane gas or you will pop o2 sensor codes. Well I lied turbs out mine is the superchips and the boys is the hypertech anyway I am impressed with the superchips handheld.

Well I ended up getting the Superchips handheld, I got it for the same price I was going to pay for the hypertech.
