KD Custom ECM programming for Duramax LMM
Single level tuning for the Duramax LMM. Tunes available to produce anywhere from 40HP economy/tow, 70HP Perf tow and more. While economy gains cannot be guaranteed, the economy tune has been producing very consistent mpg numbers at around 19-20mpg and sometimes more for single wheel trucks. Smooth shifting, low EGT’s and more power/response than many 80 and 100HP rated generic tunes.
