Hey my dad has a 04 f150 and runs lean with a k&n CAI installed. Is there a way to tune it with the hypertech 3 programmer? K&N recommended the programmer but so far no luck, it still runs lean. Anyone have experience with this setup?

 

Hypertech is programmed for a stock intake. Are you sure they didn't say Xcal 3 by SCT?

You should not use the CAI on a 2004 until you get a custom tuned Xcal3 or a custom tuned Gryphon.

 

Yeah, they actually gave him the part# for the hypertech. He called k&n & they simply told him to take the CAI off. Great customer service. Was hoping there was a quick fix that didn't cost him another 300+ dollars.

 

Sorry. Not for a CAI. It is really important to have custom tunes on the 2004s and 2005s with a CAI. Not only that, the CAI does not do a lot without a custom tune on even later models. The parameters in the PCM need to be changed to take advantage of the extra air.

Even at best, a CAI is a minimal return for what it costs. Your better option is a good tuner and the home adaptation you will find in the How To section.

 

Thanks for the help blue, guess the CAI will collect dust in the garage

 

Resante,

It's always been my understanding that on the 04 F-150s you don't need a tune to compensate for a cold air intake due to the placement of the MAF compared to the 05-08 trucks. That said our tune 04 F-150 doesn't compensate for a cold air intake and on our programmers that do you're given the option to select like 1 of 10 cold air intakes we support when programming the vehicle.
