H&S to HP Tuner Migration
I have a old H&S Mini-Maxx installed on my 2008 Ram 6.7L now. I just purchased my HP Tuners MVPI2 Pro. Has anyone migrated from an H&S Tuner to a HP Tuner? Do I need to flash my H&S back to stock, then read it with the HP Tuner to modify it or should I be able to read the H&S tune I am running with the HP Tuner? I don't want to mess up the license with my HP Tuner. Every thing I have read shows I should be able to read my existing tune and apply the license to my truck when I connect and try to write an edited tune.
FYI, my truck is not stock. I am running an 2nd gen swap turbo and all deletes. The injectors and CP3 are still stock for now, but I have a aftermarket lift pump and sump. Grid heater is gone. Fuel rail is plugged.
Any advice on how to migrate with the least headache would be appreciated.
Thanks
