Can you install bigger injectors without tune?

In general, injectors need a tune. Otherwise, your ECU is trying to drive the new, bigger injectors using the duty cycle and dead times for the old, smaller injectors, which means too much gas potentially at the wrong time (i.e. – running rich and potentially missing).

Can you run bigger fuel injectors on a stock car?

You can;t do a stock tune unless you can fool the ecu into thinking it is getting more or less air. If you throw in bigger injectors it will hold that injector open for the same amount of time as the smaller injectors and it will dump TONS of fuel in.

Are fuel injectors part of a tune up?

CLEAN DIRTY FUEL INJECTORS AS PART OF TUNE-UP Dirty fuel injectors are a common problem that can hurt engine performance, fuel economy and emissions. Many experts recommend cleaning the fuel injectors and intake system as part of a tune-up.

Do I need to retune my car?

BOOST LEVELS. In order to create combustion, a motor will use a mixture of air and fuel. In most circumstances the air to fuel ratio will remain in its target value and will not require further adjustment. There needs to be significant changes to the system to throw this values so far out that a retune will be required …

How much HP does fuel injectors add?

The technical answer is yes; fuel injectors can add 10 extra horsepower at peak. However, for some car owners, that minimal difference does not offset the increased cost and complexity of switching to fuel injectors or upgrading the existing stock fuel injectors.

What happens if your fuel injectors are too big?

Bigger is not always better It’s easy to fall into the trap of thinking that bigger fuel injectors equal more power, but unless your engine is set up to deal with the extra fuel, you’ll be on a fast track to trouble. The excess fuel will flood the engine and it either won’t run at all, or will be running too rich.

Is spark plugs the same as a tune up?

What is generally considered the tune-up today is just the replacement of the spark plugs. The tune-up is listed in the Recommended Maintenance list as a preventive maintenance procedure at a specified mileage. Some vehicles have what is called “coil over plug” ignition systems.

What replaces an engine tune up?

What is Included In a Tune-Up?

• Replace spark plugs and wires/coil boots.
• Set ignition timing -if applicable.
• Replace engine air filter.
• Replace fuel filter – if applicable.
• Clean the throttle body – if applicable.
• Perform a fuel system cleaning.

How much HP does a tune add?

To give a ballpark figure – if you are on a stock car, you could probably gain 10-15 horsepower from a dyno tune. However, if you are running on performance parts like exhaust and turbo, then 50 horsepower gain is possible – even more depending on your engine and what performance parts you equip.

Do you need a tune with a cold air intake?

A cold air intake is a cheap and easy upgrade that does not require tuning. It will work well, without a tune and it will not cause any damage to your car if not tuned.

Do bigger fuel injectors make a difference?

Larger throttle body and injectors A larger high-performance throttle body will deliver more horsepower. Depending on what type of engine you have, you can gain as much as 10-20 more horsepower and comparable torque. There is a catch, however. Also remember that a larger throttle requires higher-flow fuel injectors.

What size injectors do I need for 500hp?

Flow Rate Definition, Calculating Horsepower Range

Injector Flow Rate	Naturally Aspirated Engine	Engine w/ Power Adder
30 lbs./hr.	350-450 hp	300-375 hp
36 lbs./hr.	425-540 hp	350-450 hp
42 lbs./hr.	500-625 hp	410-525 hp
46 lbs./hr.	540-690 hp	450-575 hp

Do new injectors need to be installed before a tune?

If you purchase them new, you should not have to do this. Injectors can be installed as well on the day of the tune if you need this done for a charge. If you install the injectors yourself, please make sure they are secure in the intake manifold and in the fuel rail with good if not brand new o-rings.

Do I need to retune my engine?

If the engine is flowing better on the exhuast side…It should be pulling more air though the MAS which the car will see and add fuel when needed, the car will still try to maintain the proper air fuel ratio, and untill you max out the MAS. Untill you change the VE of the engine you will not need a retune.

What do you need to know about car tuning?

First a basic beginners guide introduction into world of car tuning and what you need to know: The ECU of your car is like its brain. For your car to deliver it’s best performance you have to keep it in a fit condition at all times. This is the only way to ensure that you get the best in both driving as well as handling.

Do you get excited about having a tune for your car?

Just becuase the car didnt knock on the dyno doesnt mean it wont knock on the street. The stock tune is richer for a reason, it takes into account increase load and extreme temps. I think people get excited about having a tune for their car.
