I've got an 05 pure stock GT with 5EAT.
I'm picking up a used WRX STI up and a invidia dp.
The shop is AWD Tune here in the DFW area. I know a tune is mandatory but should I let the shop do the tune($350) or do something like an Infamous tune from this site?
Thanks guys, I'm excited to take this first step. Any tips are greatly appreciated!
