Another strong result today teaming up with Slone’s Performance on this 2018 Mustang GT MT82! 🔥

This setup came in with:
• Cobra Jet Intake Manifold
• Twin 69mm Throttle Body
• PMAS Cold Air Intake
• Long Tube Headers
• E85

After the retune, the car picked up BIG numbers running in 4th gear:

📈 Before:
436 HP / 378 TQ

📈 After Valor Motorworx & Slones Performance retune:
484 HP / 423 TQ

That’s a gain of:
⚡ +48 HP
⚡ +45 TQ

The combination absolutely woke this car up from midrange through the top end. Stronger airflow, cleaner calibration, and the E85 setup putting in work exactly how it should.
