i was just wondering what is the best reccomended tuner for a 1999 f150 with the 5.4l?

 

The general consensus around here is the following:

You DON'T care about gauges - XCal2
You DO care about gauges - Gryphon

Otherwise they are pretty fairly even, unless you have a specific person you want to go for to do your tunes, then you may have to choose based on which product they use/tune for.

 

If you're looking for good power gains, 1-2 MPGs, and more end user adjustable
parameters than most tools offer, check out the Predator:

It doesn't hurt that they are very affordable too....

 

Mike I tried to buy a Pred for my truck in '07 and found that my PCM wasn't supported so I went with another brand. Now seeing your post I did some research and saw a update has been made for $99, my question is can I buy a Pred for the normal price with my version loaded or would I have to pay a extra $99?
This my link on the Diablo site: http://www.diablosport.com/index.php...ghlight=torkum

 

Are you looking for a product that has canned or custom tunes? Or both?
Look at the links in my Sig for options.

 

Wow, that was old.

Looks like RHAG7 was a new calibration at the time, but it has been added as far back as I could find.

Any U7153 Predator will come with this update on it, and if it is an older unit, it can be updated from our website for free, so there is no reason it will not work for you now.

Let me know if you need anything else.

 

Thanks Mike Old post? I've been around here for about 5 yrs and a Pred is on my "bucket list"

 

Nice, lemme know when you're ready to kick that bucket, and we'll get it tuned up.
