the concept is the same One Large pizza cut in 4 or the same One Large pizza cut in 12
The main contributor was the fact that 12 hole injectors atomizes the fuel better which causes more of it to vaporize, after all its the vapor which burns not the liquid fuel With more of the fuel being burnt and not being put out into the atmosphere as unburnt hydrocarbons the engine runs more efficiently. That’s the main point of running 12 hole injectors.Good feedback, thanks!
Do you happen to have MPG logs? I've got a large set for my own 100's, but would love to start compiling others and see if we can find some consistent improvements. IE Premium/Regular, 12/4 hole, tire size, bumpers, etc...
**Edit I should add: The difference felt in situations like yours is possibly the result of old, slightly dirty injectors and new, clean injectors. Could be 12 vs 4, but without back to back testing of a cleaned 4 hole, hard to tell what the main contributor was.
This is not an unusual experience
