Just sold my 1715 running "Max Performance" tune for the Xcal2. Was wondering if anyone else has done the same, with the same mods otherwise, and what differences they noticed. I am doing a new intake, port / polish, Denso's, fans and pulleys at the same time, so I won't have a very good idea myself. Just curious...that's all. Thanks.

 

Hi. Yup... I did. Was the 'old pre-tritune' 1715.

While 'seat-of-the-pants' comparisons are really subjective ( not to mention highly imprecise ;-)), I can report much improved shifting, throttle response and overall ... well, how others have described it... the truck feels 'lighter'.

I've got similar mods - the tuning ties everything all together nicely.

No complaints here.

Cheers
Vic

 

i got rid of my hypertech 3 for a 9100 custom tunes on my 03 do to major mods in air and feul (90mm maf 24# inj) (9100 way better)

 

Do you have a blower? If not, did you upgrade injectors and MAF because you exceeded their capacity with bolt-ons, or do they offer increased performance on a lightly modded engine as well?

 

Hi Jackal;

Conventional wisdom suggests that, after *custom* tuning, intake, exhaust, e-fans and under-drives, a 5.4L is maxing out the injectors, fuel pump, and possibly even the MAF.

Don't know if this holds for a 4.6L but probably not, as I have that config and am not leaning out (yet ;-)).

So if you consider that combo as a definition of 'lightly' modded, then on a 5.4L the answer is 'yes' to the former.

Obviously a retune will be necessary to accomodate the 'fuel system upgrade'.
Mike Troyer sells a kit I think.

Cheers
Vic

PS - Hiya Bigtruck, how ya been? Know any good exhaust jokes ?

 

Just wondered...Mike said the 4.6 obviously has more headroom than the 5.4. Should be good for another 25 HP or so before needing those upgrades.

 

to answer if i was maxing out my maf and inj. yes i was and i am about at the max for my fuel pump also this is all at the higher rpm, right now i am putting out 344 hp at the flywheel, if i go any higher i will need a new pump, and no i dont have a blower all bolt ons and tuning, getting another 5 or so horse power from Mike Troyer in the mail this friday, he is dialing in my tuning so it will be sqeuzing all the horses out of my combo that it can

i have been good, the Marines got me moving around alot that why i havent been in here, how are the magnablows doing?

 

[HAVE A 4.6 SCAB 4X4 2005 F150 XLT
SUPERCHIPS 1745 AND AIRAID CAI
ANY OTHER MODS RECCOMENDED tried xcal 1 but fried pcm
troyer refunded and warranty covered it

 

What's the 1745? Fried the PCM? Ouch...

 

superchips 1745 wrong data in xcal 1745 works really well

 

any other mods

Hi Jackal,

If you do a SEARCH for this, you will find a good number of posts form those who were using the 1715 and who are now using our custom tuning in 1996-2003 F-150's - both 4.6's and 5.4's. We have done that for a good number of people over the past couple of years, and a number of them have posted their results here - people like "watsonr," and Phil Kanarkowski (hope I spelled that right, & I forgot his screen name here) are among those who made detailed posts of their before & after comparisons, just for a couple of quick examples.

And yes, the 4.6's do have significantly more head room in terms of the mods they can do before they have to upgrade the fuel system - and that is simply because they make significantly less power in stock trim than the 5.4's do (notwithstanding the 1997 & 1998 F-150's & Expeditions which got the earliest 235 HP non-PI 5.4's). In general, it';s at about the 310 HP (flywheel, not rear wheels!) level that you need to upgrade the injectors - the fuel pump will give a little bit more, as will the MAF meter, more so in the newer trucks like the 2001-2003's.

Generally speaking, if you are going to exceed the 310 Hp flywheel level, we like to see the injectors, MAF meter & the fuel pump upgraded, to properly support the needs of the engine.

Now in Jesse's case (bigtruck311), he has a 2003 5.4 F-150, and at 344 HP at the flywheel, he's pretty well maxed out even the newer fuel pumps (though underdrive pulleys & E-fans do reduce fuel demand a little bit, so sometimes that will get you by in a marginal situation). In those 2001-2003 5.4 F-150's, the MAF meter & fuel pump can sometimes support as much as ~340 HP or so, but I really don't like to see them pushed to the max like that - you never want to exceed about 90% of the fuel delivery system's capacity (and doing it "right" really means not exceeding about 80% or so if you do it "by the book"!), and you never know when you're going to tow a heavy load up a grade, or do a high-speed run, or race another vehicle, etc., and it's always better to have some real headroom in the fuel delivery system!

So the bottom line is, if you are going to exceed about 310 Hp flywheel, we recommend upgrading the injectors, MAF meter & fuel pump in the 1997-2003 V8 F-150's (the V6's need injectors long before that!).
