Default Phoenix and a Ford HD 4R100 transmission
My truck ('01 F-250 7.3 PSD 4x4) has a HD 4R100 auto transmission in it that replaced the original standard 4R100. it also has a Ford AIS intake and MBRP 4" exhaust.... Otherwise stock.

Would I get a chip with Sandard Tunes or is the HD 4R100 considered a modified transmission requiring Custom Tunes?
