Budget Turbo 5.3L Yukon: Getting Uncle Rob Ready For THE PEOPLES TRACK! Final Tuning & Preparation!
What happens here
The full-throttle test revealed that the engine was 'killing it' (stalling) during hard acceleration, and the transmission was slipping. It was discovered that the cooling fan wiring had completely disconnected from the battery terminal, necessitating a reconnection. It's also recognized that the stock fuel system regulator and the 4L60E transmission's line pressure need to be addressed for the vehicle to reliably handle the new power. A quick, temporary fix is implemented for the fan wiring by pushing it back onto the terminal.
Goal: Temporarily fix fan wiring and plan for fuel system/transmission upgrades.
