HPTuners and Digital Horsepower and the main programs and interfaces that can be used to tune the factory PCM
Here are some of the pros and cons to each:
| HPTuners | Digital Horsepower | |
| cost to tune 1 pcm | $400 - $700 | ~$300 |
| additional cost to tune another PCM | $100 | $0 |
| ease of use | Easiest to use | A bit more difficult |
| support level | supported by HPTuners themselves as well as their forums | only community support |
| live scanning | yes | yes, but it's quite buggy. Need to use a community tool called UVScan |
| supports additional inputs for scans | need pro version | yes |
| in tool scan playback | yes | yes, but it's garbage. Need to use excel to read the data in a useful way |
| scanning possible without laptop | with pro version | no, need laptop connected |
| bluetooth support | with pro version | none |
| tuning capabilities | can do most needed things | can read and edit every known table with a community tool called tinytuner |
| ease of sharing | can only share with other hptuners users. File formats are proprietary | all files are .bin files or .csv files. Really easy to share and modify |
| bugs? | Not really | Yes |
