well towing a 10' wide load today, i think i finally had an injector go bad! not bad considering its got 211k of heavy towing and only 1 previous bad injector. i think i'm going to replace them all considering the miles i been putting on this truck (120k a year!). so, stock replacement get the best milage? i run a dp tuner chip, exhaust, and cold air set up. i'm looking for reliablilty and fuel milage not so much power.

 

my guess would be stock. but i could be wrong.

 

thats what i'm guessing but just wonder if anyone did some actual before and after testing. my buddy has a little bigger than stock injectors and he gets better mgg hauling the same loads, but its a stick truck so a little hard to make a fair comparison as my stick trucks get better than my automatic obviously.
