quite confused on this, need to pick up 50# injectors for my whip, and thats the last on it before i take it to get tuned. but they wont install 60 # at tune time unless its on an 05 ss. but mines an 07 and theres too much fooling around wiht the ECU for it? he said theres no use for them anyway, but anyway my question is do i need a new harness if i get new injectors, im not even sure at all what the harness does.

If you've already got after market injectors like lucas or something of the sort chances are you already have one. But yes if you get anything other than stock or gm staged injectors you will need a new harness.

^^^^ good info to know for when I upgrade. BTW, your wheels are the shit. Can you PM me the info/sizes on em?

cause on coablt performance parts it says the 50# do not come wiht harness. im wondering if i can find them anywhere else
