Which unjectors would be better to run withe vafc hack/ The 450's or the 300 whatevers?

 

the whole point of the hack is to scale down your map voltage so you can boost more without your map sensor going apeshit, which is more easily accomplished with 450's.


by the way, this should be in fuel management if you want more responses.

 

afc makes it so you can tell your bigger injectors to not open as long so yuo can put bigger ones in there with the stock ecu,... i think right?

 

Correct.

This is all covered in the Engine Management FAQ, section 2, at the top of the forum.
