Reallllllllly debating a TVS. Anyone have experience with a 2.6" setup going to a TVS? If so, is the increased in power and pull a good noticable increase? I'd likely stick with the stock pulley and 60#'s for awhile. Worth it..?

So I finally decided to buy a TVS. Should have it next week!
I'm going to run on my 60#'s for awhile with the stock pulley and see how that goes.
Do I need one of those fuel pump rewire kits?
Also, is there any TVS specific things that need tuned for? I'm assuming I can adjust the MAF scaling and timing a bit with my existing M62 2.6" tune and the car should run pretty good. Anything else I'm missing?

Yes, sir
Thanks! If I get 80#'s and drop to a smaller pulley at which point would I need a rewire or other mods?
I'm trying to get away with reasonably safely running a TVS as much as possible with a conservative tune. I want to stay away from meth and a return style fuel system for now. How small of a pulley can I run on 60#'s and what about 80#'s?
