Best Intake Manifold Upgrade for 99 5.3 Silverado
 

I got a couple issues if anyone has some experience or advice to share please do. 1st I recently logged my injector duty cycle and found its maxed out at only approx 75% TPS. I need bigger injectors. 2nd. I would like to upgrade my intake manifold to a nnbs intake manifold but if i do what year truck (NNBS) intake manifold do i need to shoot for while searching for one to buy. Ive head the 07's have #36 injectors and im pretty sure they would be big enough but im not sure if thats the right year to be looking at for an intake manifold.

Ive done the swap and I dont think its worth the cost.
