ok i have a 04 f150 xlt with the 4.6l in it know baby v8. it has around 106k on it. what can be done to the 4.6l short of spray, turbo or super charger to get the most power out of it? right now i have a k&n cold air intake and true dual exhaust. i am looking at programers but not sure what one would be best. id like one that i can change tunes on the fly like the edge. how much hp and torque are these motors able to put out without turboing or super charging?

 

Cool story, bro. Tell it again.

 

Well, some/most of the spam is gone. EsJayEs, -edit that spam from post #2, - delete it ehh.. So no one hits that link.

 

Don't waste your money on a tuner. The gains are marginal at best, and not at all noticable. I have the 4.6L and tried a Hypertech tuner, but couldn't feel any difference.

The short answer is that there's not much you can do to get more power. It is what it is. You may run into people that swear by these tuners, but I'm convinced that it's a placebo.

Not bashing the 4.6L. I find it's quite adequete for daily driving and towing. The heaviest I've towed was about 6,000 pounds (Explorer + flatbed trailer) going through the mountains of Western Maryland. It did just fine.

 

I beg to differ - if your only reference or metric is that completely useless Hypercrap, you really can't speak to the results obtainable from a properly done true custom tune. I had a 4.6 - and the SCT custom tunes from TP woke it up. Premium fuel tuning is required for best results since these engines do not have VCT. I've run standard canned tuning as well - (a 1715) and I can confirm there is simply no comparison. None.

Properly done, a custom tune will allow yer 4.6 to approach the stock rwhp of a 5.4. It WILL still be lagging in the torque department - no real way around that given the displacement diference.

The other, equally important changes involve elimination of many of the factory PCM quirkiness - Open loop delays, laggardly enrichement, and even, for some calibrations, a complete refusal to go open loop at all. On top of that is the complete transofrmation of the shift schedules, higher shift points to allow the motor to drop into the next gear in a more optimum portion of the power band, beautifully progressive shift frimness, etc, etc.

The Hypercrap is not even on the same planet, let alone in the same league.

To help address the toque deficiency, if you are planning on towing, a gear swap would be very beneficial.

Exhaust and intake buys you next to nothing.

OP - A real good read - focus on ALL the posts from Mike Troyer: https://www.f150online.com/forums/ch...ner-4-6-a.html

Finally - no flash tuner for a gas engine will allow changes on the fly - you must turn off the engine, reflash the PCM and restart.

Good news - if you have an Edge, you can simply get it converted to a Gryphon and enjoy PHP's stellar custom tuning - no need to buy a new device, just the tuning. See PHP's site for details. www.gopowerhungry.com

Good luck!

 

thats the ones i was looking at was the gryphon i couldnt remember the name of it.

 

I'd say use the search fxn, but it isn't working...

 

Sure it is.

How do ya think i found that linky in my post?

 

Short of SC or turbo, a tuner with custom tunes is going to be your best bang for the $. MGD laid down some good advice about tuners. Once you go tuned you don't go back

 

i was thinking about getting a gryphon when i start this new job after i buy new tires. tires and brakes come before performance i guess. unless i can find a used gryphon for cheap.

 

I believe there is one in the classifieds for sale currently.

 

i saw that one. im broke right now every penny im getting right now is going to gas or new tires. hopefuly this job comes through quick i hate not working

 

Not to hijack this post but I'm guessing that all the different available tuners do not void your warranty correct? I want one but not if its gonna cause issues when repairs are needed.

 

If the tuner is at fault for something breaking then your warranty will not cover the repair. It is up to the dealer though to prove it. If you are in the USA then google the magnason moss act. Not sure if that spelling is correct.
