Either way with high boost every little bit counts IMO. I think your experience is like evreyone elses with pretty much anything, some get away with a shift kit 60e behind 500rwhp others(like me) kill a fully built one with 320rwhp.

I care most about transient response when the truck is already rolling. I have 4.10 gears and was going to try to run the stock converter. I am not opposed to changing things down the road to optimize the set-up, I want to get going with the least modifications so I can choose them later on.
I made a decision to keep a smaller cam, and use boost to make power. That way I still get pretty decent daily driver manners, and lots of up until the cam runs out. I don't care about that though, I don't often hit 6+k rpms anyway (and my cam is good to the 6600s anyway). Just make sure you get a high lsa turbo cam, and that will actually help street manners. Oh, and when I was running 60 high z injectors I got around 9mpg (very much city driving though), that went up a bit with low-z 75s but one blip of the throttle killed any gains in mpg With the 95s I expect to become fast friends with the gas station owners...

I will give FLT a call and ask about that converter. I am resistant to running a higher stall because I already have 4.10 gears and relativly small tires. Will the truck still act kinda stock in low speed around town driving with the PI converter?
17-18mpg is better than I can get in my almost stock NA daily driver w/ 24lb injectors. LOL. It is a 3/4ton and has no tune though.

The cool thing about the turbo stator is that your stall speed can be relatively low -- mine is 3k -- but you still get the benefits of a higher stall in terms of spooling.
