is it needed? from what i read it is mainly used for 215 pumps because they have such stiff springs. for my app in my sig will it help anything? some say yes and some say no from the searches. thanks guys in advance! brian.

 

the kit replaces the stock afc springs with either a light spring or a tight spring. It will allow the afc foot to stay back longer ( meaning more boost is required before fueling starts).

for what you have I would say no. If you go with a bigger injector/ turbo combo than yes it could help.

 

cool thank you! for you help
