Hello all new to the forum. I currently have a 2017 silverado with a 6.2 up next for some tuning work. My questions are if it has been tuned by diablosport will i need to purchase efi lives aditional unlock strategy? Also even if returned to stock will i have issues with flashing? I did an E38 in a 13 avalanche after removing diablosport programing and was only able to flash using 7.5 edit tool. Thanks any insight before i tackle this would be great
