Question about performance chips
There are a variety of softwares available right now to do this
Vinci Handheld programmer
Diablo Predator (another hand held unit)
HPP3 (hand held... crap)
Then you have some more powerful tuning software that lets you modify much more stuff in the PCM but you have to do the actual tuning yourself...
www.hptuners.com makes such a product amongst others
The full blown tuning software has a much higher learning curve but there's tons of info between this site and other internet resources to learn the basics
If you just want a handheld i'd go w/the diablo ro vinci units ... be careful buying them used though.. not sure how the vinci unit locks to the car, the diablo unit I believe you have to pay 50 bux or something to have it unlocked for your car... hpp3 has to be completely removed from thje previous car to work on yours... all are year specific too (all the handheld)
