Hi Everyone

I have a 2004 5.4l f150. It has a K&N CAI i recently bought an edge evolution. I was trying out the 0-60 test and i noticed that when i have the edge on lvl 2 i am slower the stock by more then 1.5 seconds. I am not sure whats going on. I have changed the gearing cause it was set for 3.73 an i have 3.55s Is thier anything else i should change?


Thanks

 

That is not normal. I would be very careful with a CAI on a 2004. You need custom tunes to keep from running lean. The Edge is tuned for a stock intake.

 

Isn't level 2 towing?

 

Yes, but it's very torquey. I would think the 0-60 time would be improved, not worse. Level 2 drops off quickly over 2000 rpms.

 

Ya i have herd of them running lean with a CIA. The truck has a new motor in it now and you kinda have me worried should i take off the intake? or is thier anything i can change with the edge?

 

Get a custom tune from www.powerhungryperformance.com. They can convert your Edge to the Gryphon and write a tune for your truck. In reality, you are not taking full advantage of the CAI without a custom tune to adjust for the available air.

If it were mine, I would put the stock intake back on and convert to the Gryphon, then put the CAI back on.

 

Alright thanks for the help.

Hey Blujay what were your time befor and after you got the custom tunes?

thanks

 

I never checked my times. I don't race it, just drive it pretty good.

 

I have a friend who's 2004 F150 burned up a valve while running the Edge and a S&B cai.

 

Back in late 2004, Troyer did dynos on some stock 2004s and said they were in a near lean condition from the factory. So any additional air could be a problem for them.

 

ya i have herd that from a few people we have 2 04 f150 and both of them have CAI . Will thier be any indication that the truck is lean, will it trough a code?

 

They could throw a code if it's severe enough, some on here have. Or it's possible that you will hear a pinging if it's severe enough, but my understanding is that it can be kind of like high blood pressure. A silent killer that can be there and slowly destroy your cylinders, pistons and valves. Yours could be fine, but if it were mine, I would not take a chance with a CAI and no tunes. Just not enough reward to warrant the risk. I have an early 2005 and I just never wanted to risk it. I eventually got custom tunes and just never parted with the cash to get a CAI. I recently did the self mod to the stock intake and it seems to be doing great.

 

okay sounds good i had to recently rebuild my motor. i have about 10 thousand k on it so far so im thinking ill take of my CAI untill i get my tunes. Better to be safe then sorry.
