Well, I talked to Mike at Yank and after describing my set-up, etc, he thinks a PT4000 would be a good choice. I noticed alot of people have PT4200's, and I was wondering if there would be a big performance difference? I have an all bolt-on car with heads/cam and will have 3.73's, and alot of people think the PT4000 will be best suited for me. However, I dont want to be kicking myself for not going higher after I get them, so is there a big performance difference in e/t's or not. If not, I suppose the extra tightness of the PT4000 will be better for me, but if my et's will be greatly improved with the PT4200, Ill go with that. Any opinions?

I have had both in my car. You can not feel any difference in daily driving; both are loooooose. I like the 4200 but the 4000 would be a good choice for top end racing on the highway because of its efficency.

I run a TP4200 and love it, I really don't think there's much difference between 200 rpm of stall. I was going to opt out for the 4400, but I heard there's little to no difference. The choice is yours, daily driving=4000, weekend warrior=4200+.
