Taming 350% injectors for the street

[EverydayDiesel]

is a 350% the best option?

To get the spray angle I need I basically have two options
1. get 350% injectors (everything else stays the same)
2. convert everything to a 5.9 ecm and run late 5.9 injectors (this seems like it has great potential to be problematic and will be more expensive with the 1k conversion harness)

Other than the money for the ecm, harness and injectors, the cmb849 will give you everything you'll want, especially rpm

Well after initial research I find that I am stuck on step 1.

1. Order harness from fleece - (fleece no longer sells this harness)
2. Buy a CMB849
3. Flash 5.9 file with proper settings (some keys dont work)
4. Get 5.9 alternator (or convert the 6.7 alternators electronics to 5.9 so the connector will fit)

You called to confirm they don't sell it?

And what keys are you talking about in step 3?

Fleece said they have a few more left in stock but they will no longer sell the harness because you can now tune the 6.7 for higher rpm.
He also said that with compounds the 350% shouldnt be that bad.

The rfid chip in the key to start the vehicle doesnt work on some trucks (if i remember right its called SKIM in efi live)

You cannot get high rpm on the CMC controller unless you build your own cax.

And I've tuned several swaps without key issues
