What happens here

Following the initial dyno pull, the tuner makes adjustments to the engine's programming to correct the lean air-fuel ratio and optimize performance. With the revised tune, a second dyno pull is performed. The vehicle's engine sounds noticeably more powerful, indicating successful adjustments. The new dyno results show a significant increase to 435 horsepower and 463 foot-pounds of torque, generated with 10-11 PSI of boost from the Forced Performance turbo. The host expresses satisfaction with the stock fuel pump's ability to support this power level.

Goal: Optimize engine tuning and achieve higher power output.
