2003 silverado 4.3 "calibration file not found"

[korbin]

i recently bought the predator p2 for my 2003 Silverado 4.3, i tried to use it on my truck and all it says is "calibration file not found". i have tried to update it multiple times along with making sure the update tool is up to date as well I've un-installed and reinstalled the update tool multiple times to make sure. when i plug in my tuner to my computer it says its up to date and sometimes will have an update that doesn't seem to make a difference. ive had this tuner for well over a month now and regularly try to update it but have had no luck and is still giving me the same message along with it still saying its up to date. any help would be greatly appreciated.

Because that 2003 4.3 v6 truck is not a supported vehicle... can't do anything for that truck...

Mine is for 1999-2017 trucks with 4.3L, 4.8L, 5.3L, 6.0L, 6.2L, and 8.1L motors so I would think it should work

Nope, not for a 2003 model year... The 4.3 v6 is only supported for 2014 - 2018 model year trucks... Your 2003 4.3 v6 is not supported at all, by any Diablosport programmers... ----- can't do anything for your 2003 v6 truck....
