Both of these guys can educate you in ways you don't know about. If you already knew, you wouldn't be asking for a map.
Unless your car is identical to the other guys, then getting someone else's tune is rather limited in use.
24lb injectors are a little small for a turbo unless you're running very low boost, like ~< 4 psi.
(And I +1 the idea of selling the Miller and getting an MS unit.)
