- All Stage 3 assemblies are stock buckets that have been rebuilt and may show signs of being disassembled and rebuilt. They are all flow tested and verified before being shipped.
- Upgraded pumps pull more current, so if your EKP (LPFP control module) is weak, it may overheat causing it to shut down and need to be replaced.
