Default Using multiple Tuning devices danger?

Hello i was planning on getting HPtuners for my car but my car was base tuned with LS1EDIT will it be a problem if some little changes were made with the HPtuners when LS1edit was used?

I had LS1 Edit and then, upgraded to HP Tuners. I had no issues with using HP Tuners with a LS1 Edit Modified PCM.

I went from LS1Edit tuned T/A to HPTuners.

HPTuners will save your LS1Edit tune as the 'stock-base' tune - and then anything from there on out will be in HPTuners format

My car's been from Hyertech, to HP Tuners to EFI Live. As they mentioned above, each program will read your last program and save it as the base program. If your setup is really messed up, HP Tuners and EFI Live both have stock files that you can reload if you're interested in starting from scratch.
