Tuners
plus, by getting a tune and getting your fueling dialed in properly, your engine will actually be running BETTER/more efficiently than stock...
AND, you can even go through emissions testing with the tune installed, it doesn't affect anything emissions related... so, no worries...
and as was mentioned above, when it comes to handhelds, the Diablo Predator / Trinity are the best bet... they offer better performance gains, the most adjustability, the ability to get custom tunes written for them/your vehicle, etc etc...
trying to compare a handheld to full-blown tuning software like hp tuners, is like comparing apples to bananas... they are two totally different applications...

For the average person the HPTuner is spendy & there is a learning curve for a do it yourselfer. By far the best way to go if you know what you are doing or pay $500 for a dyno tune.
