curious if the 8.1 injectors are a direct replacement for the 5.3??? mine is a 2006 and we are putting a 216/220 cam in it and the old injector were already cycled out with the stock cam. If they are a replacement, what is the gm part number??? will these help it over the stock injectors?? thanks for any help

 

yes they are but u will need a retune

 

cool, blackbear did my first tune and he is having to retune when i do the cam swap. thanks
