Remedy 5.3 vosc reduced engine performance p1456

Seems to fix my reduced engine performance. 03 suburb 5.3. Not perfect quality. Some metal flaws and scratches upon delivery. But installed and working. Decent value and seems to have cured the issues. We'll see how it holds up as it's only been trucked 75 miles since installation.

Cons
  • Expensive
