intake or programmer?

[Jones50]

Hey all, just want to do something on my truck with 300 bucks to spend, found a Bully Dog intake for $290 for my 2008 6.4L powerstroke , does it make a difference or do you recommend saving up for a programmer or something? Thanks!:thumbsup:

Product description:

The RFI is an advanced airflow induction system built to increase the engine’s ability to breathe; thus increasing horsepower, torque and fuel efficiency, while decreasing exhaust gas temperatures.

Most of our RFI systems are designed as an enclosed system. Our enclosed systems are designed with a few simple goals in mind: keep hot air out of the air intake stream, make sure systems seal tightly up to cold air sources from within the engine bay, accommodate a high flow cotton gauze air filter, and improve the look of the engine bay with a great looking intake. By following these simple goals we are able to provide colder air and more air to the engine. Thus providing better performance than a stock intake; the resulting benefits are improved fuel economy, more horsepower and torque, lower cost of ownership than some stock air intakes, and an upgraded look to engine bay.

Believe it or not, the factory intakes on the 6.4L Powerstrokes are actually not half bad from the factory. The real killer is in your exhaust. If you do a DPF delete its not uncommon to see 4 to 6mpg improvements in fuel economy. Problem is, you can't just rip the DOC and DPF off and replace it with a straight pipe like you do a muffler. This needs to be properly deleted with certain programmers. If your interested in keeping your aftertreatment system, then consider looking at BANKS and adding one of there programmers. They are firm believers in clean power. Not "oh he's stepping on the accelerator pedal 15%? FULL FUEL!!" However, you pay for quallity, and there products are EXPENSIVE.
