HP tuners Pricing

I've been thinking of buying hpt also. What's the main difference between standard and pro?

You can plug a wideband or any 0-5 volt output into pro.

i have a used pro editor/scanner i may be willing to part with. it is out of credits though but can be purchased from HP. let me know if you're interested and i'll figure out how much i want for it. i also have a LM1 wideband that can go with it along with the tuning school books (both beginners and advanced)

Ya let me know on the software and scanner and tunning books
