Anyone heard off HP Tuners or used them? I have a buddy that has bought one and has used it on his gasser, he loves it's ease of use and read fuction. I guess it uses your laptop to read through the OBDII port. You can make your changes offline (or just look) and then write it back to the ECM under the GM program, he says it just updates what you change and keeps the original program name (header, etc). Sounds like a flash. A guy on the HP Tuner forum says he showed an EFI guy the user interface and the guy couldn't believe how easy it was to use! He's going to bring it into work tonight so I can take a peak.
