I was in the same place as you, bought a used maggie, started looking at what I NEEDED, fuel pump, tune, etc and before I knew it, I was buying, smaller pulleys, a 90mm setup, intake, and I hadn't even installed it yet. Use the 3.4 pulley get it running right, then look at what you can do, thats what I ended up doing. The trans will hold with the stock maggie tune, but it will eventually go, you can put a shift kit and servos and a bigger tranny cooler to make it last longer, but start saving for a new, FLT is probably the best out there.
From what I gathered around this site, if you pulley way down, you get restricted at the stock exhaust manifolds, so all you do is make more heat in the blower and don't get the flow you should.
Get it running right, look around the site and you will see what to do next

I went a little different route. I did the cam, headers, exhaust, stall first and then after a year I installed the maggie with a stock 3.4" pulley on my 03' Tahoe. I saw 6.6 psi. using this pulley and current mods. I just pulleyd down to a 3.3" pulley and am now seeing just over 7 psi.. I have all the basic tranny upgrades in sig. but still believe that it will eventually submit to the Radix.
I agree that you should start with the stock pulley and dial that in first, then move onto other supporting mods.
