Am installing 408 with aps twin turbos. Have 60 pound injectors that want to install now. Currently stock fuel pump and stock regulator. Plan on staying at like 3 pounds while breaking in car will just watch boost gauge and right foot.
Also planned on keeping maf in for a few weeks also. Car would be going away for winter after that and by spring should have full fuel system with big pump and adjustable reg and be going to 3 bar speed density.

I got hptuners last year and got a bit familiar with it.I had my car running decent with the 346 with cam.

I guess could put in stock injectors for now? Again just run things at like 3 psi max and mostly be staying out of boost for the break in. At least with stock injectors would not have mess with injector constants and all that stuff.

I would think I should be taking timing way down, try to get an afr of around 11 to 1 or 10.5 for starters ? Also have to set hptuners for engine and stuff.Its a 408 but they only seem to have option to select 6.0 and not sure about the number of cylinder displacement?

This stuff is a bit confusing. Next season can take it to sister city a few hundred miles away and get it dyno tuned. We have no dyno in our city.

Keep it at 5.7L
Change Cylinder Volume to 0.83624

This I got from a Base Tune I got from a Vendor who built a 408 for one of my customers. Car runs great .

Hm maybe it dont' matter if you set the other to 5.7 or 6.0 as long as the number is right for displacement ? After all its a 6.6 and don't think that is even an option?

Ok likely try what you said.Thanks
