Wow! Those are incredible gains. I've spent MUCH more than that on a whole new cat-back exhaust to get only 20 HP on a V8 engine. That is money well spent. That's the nice thing about having a turbo. It's very responsive to tunes. On the Mustang Ecoboost, a Cobb tune can get you a nice 360 lb-ft of torque. That's more torque than many V8 engines have out of a 4 banger! You gotta love Ford.
