tuning with larger primaries~~~
 

Just wondering how sucessfull people have been with larger primary injectors?

550 vs 720cc or 850cc

Able to keep idle AFRS stable?

Low load/rpm ARFs good?

If its too much of a pain, then i'll still with either new 550s or maybe the ones i have are still good and its just he o rings that are leaking :)

Depends on your porting.

With stock or street ports, you may not be able to get PW down low enough on large injectors to keep the idle from being excessively rich.

More aggressive porting will handle large injectors (I run 720CC primaries on my bridgeport).

thanks :)
