4.3 Tune?

I searched but nothing came up relating to a v6 being tuned. My dad has a rcsb 04 4.3 and wants a little more throttle response. Can blackbear tune v6s? If so, has anyone had it done?

they can be tuned here in texas theres plenty of v6s tuned, matter of fact there was one FBO with 20s running 16 flats on some stockies i would say somewhere in the 15s which isnt that bad at all

You will get alot better throttle response and transmission shifting with a tune. Minimal gains at the track from my point of view. I say its worth it for the shifting changes.
