New to Tuning - HP Tuners
I recently purchased HP Tuners Pro because I was tired of sending my ECM off to have someone else tell me what they did to help in my LS swap. I have an ECM that I want to put a 2007 CTS-V base tune and then perform mods. I know base tune will require a "write entire" to get the new OS on the ECM. I also see that the CTS-V requires a write entire to disable VATS. Should I edit the tune and disable VATS first before the write or perform 2 "write entire" functions? Asking because I saw in HP Tuners notes where it says to try and limit that due to the possibility of bricking ECM. I would leave all the DTC's live until I have it running to help with troubleshooting.

I screwed up and didn't change the VIN. I had a VIN/OS mismatch and had to relicense the ECM. Expensive mistake... Its writable now....
