What Kinda Increase Can I Expect Out Of The Diy Cp3

 

it helped put me at the #'s in my sig with much less fuel then you have.... do you have a rail gauge? itd be easy to tell if your draining it. even as mild as my truck is i could feel the diferance driving it, if your draining the rail youk se a big diferance on the top end/dyno

 

I've read somewhere on this forum that done correctly it will give about 30-35hp. I don't really know by personal experience other than I have done this. I didn't do a before and after comparison on the dyno though.

 

I did the mod and wouldn't do it again. It doesn't help with top end the plungers can only take so much, it just fuels hard on the low end.
