New motor, Dual Fuelers, 40% honed injectors, VVT Turbo, no DPF

Oh yea EGR is blocked.

I am using PPEs tuneer for break-in and to get it started.

Thanks.

I had the 268 code. turned out than the ECM has to sync up with the injector controller (?) I think. I had this come up when I used the ECM out of another truck that I had tuned.
EFI supposedly is working on a patch.

If you have a Tech II you can copy over the injector flow rates from the GPM to the ECM. Are you using the GPM out of the new engine?

Also why not just use efi for the tunes? Instead of the PPE
Yea I just made a tune from the stock tune with efi, gonna load it in and see if things look cherry.

PPE was the only tune I had that was close to stock with the DPF delete so i used it for the time being.

also I was thinking its the use of the bigger injectors causing the codes....

The prob deff has something to do with the injectors/nozzles. Atleast in that area for sure. Pics?? Hows it feel? Good job Chad, you guys slapped that puppy in!
