I'm fixin to order the vette servo for the truck, just cause I like what it did for Taylor (Jetersaurous). I'm also thinking hard about a tune. But my question is, would it be worth it to get one on the 4.3? I know there's probably gonna be a few "just wait and put a 6.0 in it" but I won't be able to afford that for quite a while. Of course I'll make the 2 hour trek to see Allan. Everything I've heard tells me he's the best. But again, is the 4.3 worth tuning?
