Hypertech and custom tuning questions??
How it performs with custom tuning is all up to how good the tuner is.
Some tuners make is that afterwards you can't use the HPP3. Some don't.
If they do a good job programming, do it just the way you want it, and you need no further changes then the HPP3 will be worthless to you.
The power gain of a custom tune on a wideband O2 sensor dyno simply can't be approached by what some people not-so affectionately call "Hypercrap Tuning." A custom tune is right for your car instead of just being a one size fits all "tune" like with the Hypertech.
IMO, an HPP3 is a fine tool for adjusting the speedometer after rearend ratio changes, shift points, and fan settings. That's about it.
