I got a 2016 wrx, new to subaru's and turbo world, I have the stage 1 cobb tune and all stock from there. I'm looking to upgrade with a lot of bolt on's basically. If I go to a bigger turbo is it possible to run the current tune since the car already has a turbo without getting a pro tune? I know to get full potential I need to get a custom pro tune done, but I'm just looking to slap the new turbo on and keep going till I'm ready for it? Is this possible or will it hurt anything?
