My niece and Her Husband just bought an 05 F250 with the 5.4. He is thinking about using a chip called hypertech performance chip.
I have zero clue on performance chips for gassers. Can you give me an idea of how good they are, or a link to see what they do? Or your recommendation for the best/cheapest?
Ok, I'll send these links. So, with the upgraded tunes, what else would a person need to change to maximize the tunes. Seems like there is always something else? You know exhaust, intake, hair style, window tint.
A good 4" exhaust should help it out considering the truck will be dealing with more fuel.

Also for the more "powerful" tunes that they might be running, I think it's advised that you run those with 93 instead of 87 Octane, if you want maximize those tunes. I think they can still write it for 87, but it won't have the umph compared to the having 93 due to the timing(I'm pretty sure about this anyway).

This depends on what part of the exhaust is being replaced. The 5.4L requires back pressure to maintain low end torque. Too large and low end torque will suffer.

I'm not familiar with the 250 intake, but most 04-05 150 owners simply replaced the stock intake tube (Gotts mod).
04-05 F150s are also known to have lean issues and intake mods are known to make this worse (actually causing CELs). Again, not sure if this also true for the 250s.

A Gryphon or SCT Livewire can have up to three custom tunes (customized for the truck's hex code and modifications). Most owners pick 87 performance, 87 tow, and 91/93 performance but you can have any combination you want (87/89 or 91/93).
Same thing happens on diesels if there isn't enough fuel and/or air being pushed through that bigger pipe.

I'm not too familiar with my gasser mods. Diesel I would be more helpful and more confident in my answers then with the gasser questions.

That would make since, I would also imagine that alot of things would translate over to the F250 5.4s as well. How bad are these lean issues? I would imagine that a good custom tune would be able to compensate for them if it wasn't way to lean.

That's the standard 3 custom tunes on gas and diesel, however, I still keep on hearing about issues with the screen on the LiveWire, I don't know if they use a different unit for Ford Gassers compared to the diesel unit, but I still hear complaints about the screen kicking off, staying on for awhile and then kicking back off again. I thought that they were supposed to have a fix for that, but either those people didn't have the fix or the fix wasn't a good one.
Hey Tex, didn't expect to have an answer from you on this, but when it comes to performance, I should've known better. Thanks to both of you for your input. I'm trying to get the kids to get on this forum to learn about what they have.
There is so much they can learn from folks like you. And the many others on FTE.

Stock exhaust can handle any fuel (with excpetion of forced air induction). Most exhaust mods are done for NOISE.

Pretty bad with some non-stock intakes - really high exhaust temperatures and in some extreme cases - burned pistons. 10-4 on the custom tune (from a reputable tuner like PHP).

I'm not familiar with the screen on-off issue with the Livewire. For the Gryphon (re-badged Edge) this type of issue is most commonly indicating a low or weak battery condition (or less commonly a bad OBDI port or cable).
I used a SCT on my last 5.4. I tried Supechip & Hypercrap. They just don't compare with custom tuning from Troyers or some of the other good tuners around. The shifting the SCT gives is much better than the other brands. Some tuners just raise the line pressure to make the shifts firm. Its not good for the tranny. I like hypertech so much that I don't use the one in my truck. It has a shift on the fly model in it but I'm afraid to use it.
