CAT C15 Trim Code

[multitask]

Anybody here know the best injector trim code for fuel economy?

Your better off using the proper trim codes the factory assigned to your injector. The trim is only intended to balance the injectors to allow for manufacturing tolerances. Some have had limited success in this area ("farcall") but most dump in the biggest trim across the board for a small gain in hp and then live with an engine that runs rough because its tearing itself apart.

You’re right I better just go with the config of each injector. I know a guy running 5232 across all 6 and reckons she’s good, but what you said hit home. Thanks
