while i'll agree, you are assuming the person will already have a laptop. no laptop means more money needing to be spent. at least with the VHP handheld, most of the hard work is done for you. all you need to do is just play around with the fuel and timing some to dial in your setup.

here's a dyno of my wife's 99 formula i just tuned using the handheld. all bolt ons, + heads, and stock cam. car runs and drives fine. idle is great. no surging, etc...

well, apparantly, it took care of the additional airflow the heads provided. the cam will be a cakewalk from here. maybe you should try this handheld before commenting about it. this handheld isn't in the same class as the others. i'd take this over having to spend countless hours tuning with an editor. not saying you won't get better results using an editor, but you'll get better results with this tuner than with any other. 3 hours of dyno tuning trying the different options until max results acheived vs ???? hours dynoing and driving around with an editor or having someone else tune it for you and have to keep going back until finished.
