I have a 2009 F-150 5.4 3.7 2 wheel drive with max tow package. I pull a 7000 pound trailer and have a bit of a strain on long uphill grades. Want to pull trailer out West but think that I will have a problem in the Colorado mountains.
My question is: Will any of the performance enhancing products such as Bully Dog or Superchips, or cold air intakes, etc do anything to help my power and torque problems?
Thanks

 

A tuner might net you some minor improvements, but I don't think you're going to see enough improvement to make it worth the money. You're simply pulling a lot of trailer with not much motor...

 

Call Mike Butler at 5Startuning.com.

He can answer your questions re: tuners and intakes.

 

Thanks for the referral - I'll write him a note.

 

I pull a similar weight trailer with my 5.4 4x4. While Im not gonna win any races, I have high confidence in the motor. Once she's spinning about 3500 or so, I haven't seen a hill she won't climb.

But I'm also considering talking to mike at 5star. More for the shifting than anything, though

 

Sorry guys, I can't help myself. This is like Enzyte for F150's!

 

Pls do call us we can help give the truck more guts something Ford did not do.

 

The 5.4L with 3.73 gears will pull a 7000 lb. trailer thru the mountains of Colorado, but you will be in lower gears a lot. It won't win any races but it will do it. The main thing to watch is engine and transmission temps. When you get to the altitude of the Rockies the air is pretty thin. I would get aftermarket gauges installed as the factory gauges are not that accurate. A tuner will help, but it won't work miracles. You just have to be patient and not abuse the truck and you'll be fine.

 

Look at that! Answering posts on a Sunday, now thats service! I will be calling as soon as I get the money, I sent you an email the other day re: my X3 from my old 6.0 diesel and you told me its not the "enhanced" one and won't work on my F150.

 

Tim, did you not believe me when I said that Mike's service is the best?
Mike rocks, 5 Star for the win!!




But honestly, there's nothing wrong with PHP if you don't mind the 10 week wait for tunes to be emailed.

 

Of course I believed you Chandler. You haven't given me any reason not to. We took a bunch of crap to the flea market today and the CFO donated $50 of the proceeds to me. Into the "secret stash" it goes, SCT here I come!
