My bike is FINALLY dialed in. It rides like a champ, and our setups are nearly identical. Here is what I would recommend...
You could try a smaller pilot, but I bet you get what I did - major lag in the low to mid range.
I would get a TBS needle, and finish off the air box. Read my air box post that I posted last night - it has some pictures as well. If you can let in some more air, you will lean it out a little. I would also HIGHLY recommend getting TBS needles. They are inexpensive, take only a few minutes to swap in, and make a big difference in the mid range.
I am running 132/45's as well, so you should be very close to what's going to work. Also, you may want to consider drilling out the hole in your slide for throttle response... if you have the guts.
I am 3.5 turns out, and I get a very minor amount of popping on decel. I may try to dial it out, but it's so much better than before I'll probably live with it.
The slide drilling and airbox info is also on my site (the link in my signature).
