Modify stock tune with handheld, yes you can.
Taking the backup file and opening it in Advantage PRP, no. Only HP tuners can download and open the actual tune in the pcm.
And its one or the other with SCT, custom tunes, or preloaded tunes /modify stock tune. Cannot have both enabled on the X4. Yes, I have tried.
If I had to do it over again I'd invest in HP but already bought an SCT X4 and used it to tune w/Lito. Overall, working fine but I put away the SCT when not in use and only get it out when I really need to.
