First Start AFTER Texas Speed F-117 Stealth Camshaft Swap. Lt 5.3 6.2

Getting a 2015 Chevrolet Tahoe to fire up after an ECM installation often comes down to the basics. We are buttoning up the final connections to ensure this SUV is ready for the road.

This is a first start after a major engine overhaul. We Pulled the motor for a complete reseal, installed a new set of fuel injectors and called Texas Speed for a new Camshaft. No more AFM/DOD for this Gm v8 engine. VVt system has been deleted, it's all motor at this point!

The footage captures the reality of working in an independent shop, from the detailed engine bay inspection to the final road test. Whether you are dealing with your own electrical gremlins or just appreciate the methodical approach to automotive diagnostics, this walkthrough shows how we confirm the fix before handing the keys back to the owner.
