Looking forward to seeing a turbo build of your truck. I would really like to check it out before the turbo goes in as it seems like a beast already.

Meth refills just come up depending on how you set the car up to use the meth. Normally you set it to come on as the car goes into its top ¼ of boost. So if you are getting into boost a lot, then you'll use a lot of meth.
With a motor like yours if the car was setup right you could probably get around for the most part happily with no boost. So you might use a small amount, ( or you can choose to shut it off around town and only run it when you race it ) Its kinda like having N2o on a window switch preminently open.
You are gonna use as much as you use.

Like Joe said, you only use what you use in boost. If you drive it "Normal", it will last you a while. If you get sporty with it, you will have to refill more often. By the way, the blue windshield washer fluid is about $2 a gallon here. Not a huge cost to keep up with. But the benefits are great.

Pop the hood and it looks so clean, like it came out of the factory. I'm happy with it.
I'll eventually wrap the exhaust pipes I think. We'll see.
I'm also running meth, but my tuner said he tuned it safe so if I run out of juice, it's still safe. But running meth/water, it lowers the intake air temp (nothing to do with under hood temps) which increases hp. I would definitely recommend running meth/wate setup. Best bang for buck.
The injector is managed by a control unit and pump. You set when you want it to come on (I have mine set for 2psi boost) so when I'm not in boost, it doesn't kick in and waste fluid. Check out Snow Methanol Injection systems. (google).

I was thinking about an 80mm since I'm running a 408 and the heads will flow a lot of air. It will still be a daily so I would want it to bee in boost by 2500-3000. I dont know much about turbos so I don't' know if that is realistic with that size of a turbo. I could buy a built kit from kb or trick but I usually like to do things myself. So we will see what happens.
Looks like I will have to get the meth kit. I don't see a reason not to. Also I think I will put a smaller cam in pig when it comes time. It would be nice to get better driveability out of it as well.

It will depend on your power goals. I had mine spec'd for me. Asked for something that I could "Grow into" if I go forged and want to push it to 750-800 hp. If you plan on going bigger than that, then yes, go 80. Otherwise, T76 should get you up to 750 and not hurt your spool time.
Personally, I think a T76 with .96 AR would be a great starting place for you.
Also, the LS9 Cam is so streetable. 122.5 LSA drives like my stock LS1 cam. Can't tell a difference. Sooo smooth. It's just a little bigger than the LS6 cam. I love it.
