GTM Performance Engineering: MHI Twin Turbo Official Release

Sams tunes are pretty damn close on the first try, you do data logging and Sam will tweak it from there if necessary. With that said, if you can afford it getting a professional dyno tune from a competent uprev tuner is not a bad idea at all.
