8.1 liter injectors into a 5.3 liter engine
I have heard you can put 8.1 liter injectors in a 5.3 liter engine. Is this true? How much trouble will it be to do this? Is it worth the trouble, and what components do I need to do this if i decide too?

will the superchip reprogram work or do I need a custom tune, and are the 8.1 injectors even worth it?

No, it will not. You would need a custom tune. There is no point in putting them in unless your motor needs more fuel, stock injectors in a mostly stock 5.3 are fine. Now if you had a 6L and a big cam and were wanting to turn higher rpm, you would need bigger injectors. Other wise, they will do nothing for you.

He's right. Unless you're running some serious mods in your 5.3L you shouldn't need to change injectors yet. They may be worth picking up to keep for when you do need them, but you likely don't yet. You will want someone with a normal tuning software to program them in for you.
