Hope this helps .. should give you the flash file # you need.. 
OTE: C7 "Hi HP Ratings" 250HP 800lbft to 330HP KAL1-12897 were factory built with
Injector p/n 233-3535. If a "single" 233-3535 injector is replaced with a 241-3400
injector w/seals (238-8091 p/n on injector... not serviced) then "all six" injectors
MUST be updated to the same part number and the appropriate flash file and "etrim"
files MUST be installed to match the "new" part number injector! Use list below to
determine flash file based on installed injector number!
