Im thinking about getting an airdog or fass fuel system for my duramax and was wondering if i would need different injectors or anything to go with it?

 

no need for different injectors, I'd recommend Air Dog just cause they were the original fuel preporator, and FASS is actually the son of the main guy that owns Air Dog and the son actually more or less stole his dad's ideas and that just ain't cool i don't care who you are, they both come with lifetime warranties (at least airdog i know for sure does) and AirDog is a smaller package and quieter which i know you may or may not care about noise and last but not least air dog is more affordable

 

Alright cool. So I can just stick it on without anyother mods. What kinds of preformance gains will it do?

 

you will gain a bit of power because the fuel will cleaner and more pure but whether or not it's noticeable I can't tell you, I didn't really notice any performance gains, I know it helps all other mods work better together though cause it can supply more fuel than stock pumps which is a good thing, the AD150 can support up to 1000hp so basically it just makes sure you don't starve your CP3 of fuel

 

Alright I see. Thanks man.

 

yep

 

GM chose not to use a feed pump for the CP3 whereas Dodge did. Adding a feed pump will only gain you power when you have a big enough tune to strain the fuel supply you have now, which is not too hard. Having a feed pump keeps the CP3 fat and happy with all the fuel it needs. We sell FASS and have had great feedback with them. We have also sold Air Dog when FASS got behind on filling orders and have had good luck with them also. If you are planning to go big with your power look into a fuel feed line pickup kit also.
