FAQ:
How much fuel pressure does FiTech EFI need?
- FiTech EFI systems like the FiTech 70074 require around 58-60 PSI of fuel pressure for optimal performance. Maintaining proper fuel pressure ensures efficient fuel delivery to the intake manifold, enhancing engine performance.
What is the difference between FiTech and FAST intake?
- The difference lies in the design and features. While both offer EFI solutions, FiTech focuses on user-friendly, self-learning EFI systems, whereas FAST intake systems often cater to higher-end, performance-oriented applications with additional tuning capabilities.
Why does my FiTech bog down when I accelerate?
- Several factors can cause a FiTech EFI system to bog down during acceleration, such as incorrect fuel pressure, inadequate airflow, or improper sensor calibration. Checking and adjusting these aspects can resolve acceleration issues.
Which is more reliable, EFI, or carb?
- EFI systems like FiTech are generally considered more reliable than carburetors due to precise fuel delivery, better fuel economy, and improved starting in various conditions. They offer easier cold starts and adaptability to changing environmental factors.
