Working on it. I need to find out myself.

 

That's just the scanning portion of my tuning program. If you what to get lost you should see the tuning portion lol. Once you get into it it's not as bad as it looks. You can change just about anything you want engine or tranny wise. Just waiting on them to release dodge support so i can start tuning my truck.

 

Everything i found on them say they are 44 lbs. They are the same as the 5.7's. So you should be good for 10lbs boost. I was running 44's on my 6.0 @10 psi with no issues. I should be able to get the duty cycle for the 44's from one of my scans.

 

that would be sweet! if thats what they are, alot less $$$ to start out, then i guess i need to figure out the map sensor

 

Chrysler rates our 4.7L injectors at 24 lbs. According to rates based on the 43 psi system they are only 21 lbs.

Injector lbs# are rated at a standard 43 psi. So a 21 lbs injector rated at 43psi will act live a 24lb injector under 49psi.

Yes, you will need bigger injectors to tune boost as the most you can get out of the stockers is 24 lbs on a 49psi fuel rail.

Thanks for clearing that up. looks like i happen to run across some bad information. The info i found on the 08's said 44# . 21# will be no where near enough.

 

No worries, its 21lbs @ 44psi so it gets mixed up alot, lol. Our fuel rails are rated at right around 49psi so that gives us a max of 24lbs. I ran into the same issues while trying to run the blower on mine.

 

Maybe i should put my glasses on lol. Okay 2 more things to add to my list.

 

well, you may still be correct, we are dealing with the "new" 4.7, i will have to do some more digging to see what is actually in it right now
