Radium would be a good option, they have a stand alone set up on their website. I know BOE has tuned a few turbo cars as well. Member Evansp60 has been a great help to me for advice, might want to send him a PM. I currently have a turbo kit waiting to go on to the car after I buy a few more parts. If you are looking for an NA tune while you are waiting to go the turbo route, I have a CharlieX/Vision Function tune that I am very happy with. Do you know what turbo kit you are going to run? I know Vision Function has something in the works.
