will i need to mod anything?

im thinking of getting a DTR chip for my current setup in my sig and i was just wondering if i need to modify my slk-948u for it to work. i searched but couldn't find anything saying it needed to be modified to work.

im not sure if the slk-948u will work, your gonna hafta mod something, but what i dont know. there are only 2 hsf that work with dtrs right off the bat, swiftecs helicoid hsf and the pal hsf.
