do they really make a difference in fuel economy. and what other items can improve it?

 

depends on the truck. i have a full k&n cold air intake with a edge evoltuion cs performance tuner. ive also got a 6 inch lift with 35s. With the intake I get 13.5, I havent calculated yet with the edge tuner. Honestly they are a good investment and from what ive been told your truck actually runs better and uses less gas and power to get moving. It all depends on what your looking for.

 

I am looking to make my stock box ram air seems to be little better then cold air
there's a nice spot next box for a scoop

 

i have an 06 2500hd stock but i have an autozone brand intake which i think gives me a little more but im wondering if the programmer would be worth the money.

 

Well even if you get a 3hp or 2 MPG increase it pays for its self takes a bit but still

 

keep the stock box, drop in a good filter, and buy the air aid MIT intake tube. That's a cold air intake right there. you could drill a hole in the bottom of the intake box, through the steel plate and run some kind of tube to make it ram air. Don't buy a programmer. Not worth the money because they cost more than a custom tune, and a custom tune can do a whole lot more than a programmer can.

Put it like this, a custom tune, is tuned to your exact drivin habits. The tuner rides in the car with you, and tunes it while you drive. Would that better better than a generic out of the box tune that is generally mild compared to what a custom tune can bring to the table. I had a bullydog programmer on mine at one point. Even set on performance everything, it was nothin compared to the most mild custom tune I've had. I started out mild(87 octane tune) and now I have a 93 octane tune and won't look back. Saw a 3mpg increase with the tune over the programmer

 

where can u get the custom tunes ?

 

Blackbearperformance.com or gowheatley.com. One of them will do it for ya, or find a dyno tune shop around you

 

Thanks !
