Any personal experience with 2.3 tuners?

[white02ranger]

I've been looking at different tuners for my 2002 2.3 and i now have the money to purchase one. I'm most interested in the one from bamachips.com because they claim 10hp and 17ft.lbs on a standard 87 octaine tune, but i can't find any dyno charts to back it up. I'm wondering if anyone has had any personal experience with tuning a 2.3 and what results they've had with it. Any advice is greatly appreciated because i now have the money, and need advice deciding on a perticular one. Thanks
