Do you need a tune after putting performance injectors and fuel pump?
to answer your question, you dont need a tune but will your car benefit from it yes. most defintately if you change injector size.
Will my car run with bigger injectors?
No, bigger fuel injectors would not match the engine which has hitherto running with smaller injectors. Also the fuel pump would not support it. Hence not advised. Well to increase power output you will need to increase fuel input.
Why do I have a problem with my fuel injection pump?
Fuel injection problems, therefore, are one of the most pressing engine issues to deal with. Whether you’ve experienced fuel injector failure or not, it helps to understand the fuel injector pump, how it relates to engine performance, and also how diesel fuel injection pumps differ from traditional gasoline-powered units.
What happens if the fuel injector doesn’t close?
If the injector can’t close, cylinder performance is compromised. Whenever the fuel injector pump’s O-rings or ball seats are defective, the timing of the fuel transfer process is disrupted. This is a common diesel fuel injector pump glitch, and usually requires a complete injection pump rebuild or replacement.
What’s the pressure of a diesel injector pump?
Today’s diesel fuel injection pumps are under pressure – even more pressure than what was once considered “normal.” Around 15-20 years ago, it was common for fuel injector pumps to process fuel in a system at around 10,000 to 15,000 psi (pounds per square inch). But that’s only about half of what engines are expected to do today.
How does a fuel injector work in an engine?
It’s about as simple as you can get: fuel injectors supply fuel to the engine’s internal combustion chamber. The fuel is dispersed from the injection pump to the combustion chamber via a fairly simple process. Pressurized fuel enters the fuel injector.
