i noticed the s came out and said its a lot easier to program, is the B that bad? also wouldn't you think the B would hold boost better?

the stepping motors in the type S are larger, it has a "gain" knob that allows you to adjust wastegate response, both internal and external, and supposedly it's all the profec B was without the fuzzy logic leanrning curve that a lot of people complained about with the profec B.
I'm looking to get one soon.

i can't decide which one i want, i just want one that will perform perfect when set, i don't mind taking a little bit to set it up once if it stays like that...

I have never used the Spec II but I cant say that I have heard anything really good about it. I use the Type-S and I love it...very simple to use and it works like a charm
