My next mods may include an aftermarket CP3..

Question I have is do they hurt MPG?

I understand they have the potential to provide %% of additional fuel when required. If driving around under easy throttle is it using more fuel than a stock CP3?

I am planning on some Flux 1.?, cam, springs and possibly a aftermarket CP3..
I am trying to make a powerful truck that is setup for good/better than stock MPG also.

Comments? Recomendations? Isn't this fun yet...

 

No sort of modded pump or duals will affect mileage. They only supply what your injectors, ecm and right foot call for. More pump just means that when you up the ante with big sticks, and wicked programming the rail p will be maintained and you will make power not just heat and smoke from poor atomization. Jay

 

Boost,

Thanks.. I was hoping changing CP3 would not hurt MPG..

Probably do injectors and springs 1st...
Then Cam and CP3 2nd..

Need to save up some more mad money for these items..
