just wondering how many pounds per hour that they can be maxed out at in an 06 silverado with a 5.3 have been looking at doing a cam and head swap and just trying to get things in order .thank you

 

I don't know, but if you are going to change them, you may as well get 42# injectors. You can get a used set in the classifieds for $200-250

 

are they the same as the return style injectors?

 

I was told my Magnacharger that my 03 Flexfuel injectors were 38# and could have ran them with supercharger, bc that is actually how they sell the flexfuel kit w/o injectors. Bought a used Radix that already came with 42# so I never tested it.

 

Efi live says mine are 35#. I never seen more than 50% duty cycle on mine

 

What I want to know is what kind of injector are they? Regular truck injectror? Ls2? What are they?

 

i think there rated at 32lbs . they have 4 holes/

 

Hey guys. He is actually asking about my truck. I bought a set of injectors just in case I needed them, and If I don't I'm going to sell to "teamblackandred". How many pounds are my stock injectors good for? I have a 2006 RCSB Regency 5.3 2wd. It started its life off as a w/t from the factory. Thanks.

 

Somebody must know the answer.. Are all 05+ 5.3 trucks flex fuel?

 

No they are not. The easiest way to tell is to have the computer read. If the injectors are like 33lb or whatever. Or if the gas cap is yellow. And my truck has alumin fuel rails as well
