O.k....I just got my 5.4 about a week ago and LOVE IT. It currently has a flow and some duals from the muffler back. This thing runs like a champ....

Question is, what basic mods do you guys recommend that I'll get the most bang for my buck without going overboard?

Thanks...!!

 

SCT tune and a cold air kit.

 

I have asked the same question and been told to go with an AF1 cold air intake. should bring more HP and beter mileage.

 

Welcome to the site!!

As ACW said go with the AF1 intake but remember that if you get the 3.5 inch intake tube that you will HAVE to get a tune because it will run too lean/rich so be sure to get the 3" tube.

 

I concur on the AF1 and an Xcal II with Troyer custom tuning. Wakes up these trucks and throttle response is unimaginable.

 

Take the flow daddies off and install Magnaflow mufflers. Gut the cats. Install a supercharger.. new cams...bore and stroke the engine... The possibilities for more HP is endless... Other than that just do what they said.

 

What does the AF1 usually cost, for starters?

Does anyone know a good link to buy it for the best price?

Thanks!!!

 

Here ya go.

I read up on the site.....thanks for the link!!!

I wonder if that's the one with the 3 or 3.5" pipe. I believe someone told me that if I went 3.5" that I would have to buy a tune as well.

This Troyer bunch has alot of stuff!!!

 

Just call them up and tell them exactly which one you want. I have the 3" tube on mine even though I have the Troyer custom tuning. I went with the 3" tube so when I return the truck to stock for trips to the dealership I can still leave the AF1 on there with no issues.
