What can a 2015+ handle as far as stock internals? Sent from my SAMSUNG-SM-G891A using the svtperformance.com mobile app
Transmission will go before the motor will. IIRC, 450whp is the cap before you need to start worrying (transmission that is). It's been mentioned that the motor itself has been tested up to 720hp by Ford. Edit: And I second the call to LMS. I'm running their 93 tune on my MKS and it's a hoot.
