That's not how things work. Different injectors don't increase horsepower.

 

The 6.0 injectors on your truck are already large enough to make more power than the stock 6.0 can make. It would even handle mods like a camshaft and headers.

 

If you want more power, you need to add more air. So think camshaft swap or headers to increase the horsepower.

If your 6.0L is Flex-Fuel, the stock injectors are high flow.  The Flex Fuel injectors are 50 lb/hr Delphi's, and they are what a lot of people upgrade to.  Check to see if you have these injectors:

Injectors don't increase horsepower. I replied in the other thread he made.

True, injectors by themselves will not do anything.  If he has the Flex Fuel injectors they should be more than enough for whatever other reasonable mods he does.  Non-Flex injectors are still probably good enough.

Some people just throw money at their truck thinking it will add power.............Like the cold air intake, the factory air intake is a cold air intake.

Too expensive!

What about some E3 plugs?
