hey guys, sorry if this has been covered before, but i have a question on injector wiring.

my '03 ss has a radix and the 42lb injectors that came with it. if i were to upgrade to a bigger injector, do i need to re-wire anything, or cut/splice anything to do this? or can i just buy new injectors, unplug the old ones, and plug the new ones in? a couple guys over at hptuners forum say that i don't need to splice anything, but i could swear that i've heard from several people that i would. whats the deal?

oh, btw, the reason i'm asking is that my inj duty cycle is over 101%+

 

I think cut and splice.Maybe shimming up the fuel rail.

 

Yes, you will need to splice in the new plugs. The injectors you have are as large as you can go with that type of connector. There is a thread on SS.com about going larger than 42lb injectors. It has all the info you need to do it.
