Well, My wife told me she would change the locks if I started the V10/hot rod project idea before she graduates from school

...or bought another firearm (too bad she doesn't know about the LRB M-14 on the way

)
This and I am starting to get used to the power my truck has...So whats next?
I have just a pretty plain truck. 2002 7.3 with an intake, turbo back exhaust and the upgraded Injector controller thingy..oh and of course my 6 pos chip
Will bolting on a 38r do me any good without retuning? or would I have to get it retuned?
Would I find more juice with an Adrenaline for half the money? Need retuning?
Injectors are pricey...but I can always save up and get something in December...
Its either some go faster parts or converting my dually to a srw...new wheels and tires, and a bit of body work on the bed...That might save me a mpg though? Maybe not, cause I would try to go with 35's...or 37's....how much of a lift would I need.
How would I convert the speedo for the bigger wheels...
Bored at home...this is what two days off in a row will do to me...plans and plans...
