Improved Fuel Efficiency for Performance Cars

These high impedance injectors are a game changer for any performance automotive enthusiast .They provide a precision flow of fuel that results in improved fuel efficiency and maximum horsepower. The installation was straightforward and the results were immediately noticeable. The only downside is the price, but the investment is worth it for serious car enthusiasts..

Documentation is garbage. Even the FAST technical management cannot provide basic service.

These injectors work well. Documentation is garbage. Even the FAST Technical Line cannot provide the basic operating parameters needed to set up a new EFI computer. If you read the forums this seems to be a common problem. So when you buy, be prepared to take a lot of measurements yourself. For those who need information, the flow rate was close enough to what was advertised. The injector opening time was 1.0 ms

Pros
  • Satisfied so far
Cons
  • Security
