175's or 155's and upgrading to an Air Dog

Buddy and I are on the fence about what injectors to get 155's or 175's. He really does not want to have to buy a Air Dog if he doesn't have to. Could he safely run 175's on a stock fuel pump with 6.4 banjos and the Ford upgraded fuel spring kit? Or should we just stick to 155 with those mods to the stock fuel system?

Get the Airdog. The stock pump can have trouble with stock injectors keeping up with an extreme tune. Then the injectors depend on your goals for the truck. 155's for heavy towing and 175's for good street performance and reasonable tow capability.

He wants a 500hp daily driver to hit the track with a couple times a year and pull 8k-10k in the future.

For a solid 500 go with the 175cc injectors, keep it on a lower hp tune and get he air dog when he saves money, or try to get a package deal when buying the injectors. These things need to maintain fuel pressure at all cost to keep them reliable!

Most vendors will make you a deal when you buy their injectors and a fuel system. They will also extend the warranty on your injectors!
