I want to hop in and recommend Ryan @ PD Tuning. I've been PD tuned since my MS3 days and I'd honestly never consider anyone else. Going from Cobb OTS stage 1 to Ryan's base tune was literally night and day. Power, drivability, AFRs, everything just on point. Ryan is a genius when it comes to Ecoboosts, MazdaSpeed MZR, BMWs, VWs, etc.....
They even have a tune for life package now I think where no matter what you add, you just ask for revisions and you've got it.
