You're making some really big mistakes here in trying to compare your truck to these other newer & much more powerful trucks, so I just wanted to drop by to help you out by pointing out a few of the obvious factors & you'll quickly see why your truck isn't going to run like theirs.............
But first - if you read your documentation from us that all of our custom tuning customers receive, it tells you in great detail NOT to attempt to judge performance by the seat of the pants - that is the absolute worst way to attempt to judge ANY performance modification, especially in a 2.5-3 ton truck. We go over in great detail exactly how to make appropriate & accurate before & after comparisons in those docs.
You do not have anywhere near the kind of power that all of these other newer trucks in this thread talking about spinning their tires have - remember, yours is a 2001 truck that has about 50 HP less than what the 5.4 3-valve 2004 & newer trucks that everyone else posting about burning the tires in this thread with our custom tuning have - so you simply cannot compare. They start off with 300 HP, you started off with 260 HP - 5 years ago. So you were 40 HP down to start off with in stock trim 5 years ago, and even assuming absolute perfection and still making 260 Hp stock (which is usually not the case 5 years later without some very thorough maintenance including replacing all the coil packs, spark plugs, upstream O2 sensors, thorough fuel injector & EGR tract cleaning, & numerous other things), you still end up about 50 HP short of what they make comparing your truck in perfect as-new condition with our custom tuning to the new 5.4 3-valve trucks with our tuning - so you simply cannot compare with them, my friend.
And without datalogging as is thoroughly described in our custom tuning documentation as well, there is nothing to look at - we have to have actual data, not seat of the pants guesswork comparing your truck to those with much power power in stock trim.
Overall - I would suggest going back and re-reading your docs, and not trying to compare your truck to these newer trucks that have at least 40-50 more horsepower than what your truck has - focus on doing proper before & after comparisons as we describe in our custom tuning documentation, as well as all the maintenance & datalogging - that is the only way that truck will be in top condition and you can compare the performance appropriately with our custom tuning.
I hope that helps your understanding of this a bit better, as I know it can be confusing when you see what others with newer trucks talk about here - but you do not have the newer truck that they have, that is one of the most important factors - your truck makes a lot less HP and especially low rpm torque off the line, stock or tuned, compared to any 2004 or newer F-150.
If you decide to do the datalogging as we describe in our custom tuning documentation, we'll be more than happy to look at that data for you, & best of luck with your truck!

Thanks very much for your post -
I hope I didn't address my response to the wrong person!! Where my earlier comments came from was in response to a post made where the profile listed the owner as having a 2001 F-150, so that was what I was making comparisons to. In any event, some quick FYI stuff...........
One thing you'll want to know about is the importance of doing the datalogging as we describe in our instructions, especially in these newer trucks - and all of it except the A/F's can be done with the XCalibrator 2 & a PC - the datalogging is important due to the 5.4 3V's variance in it's stock MAF transfer function, where it varies a good deal more than in the 2003 & earlier vehicles, and that is something new - it's also seen in the new 4.6 3V Mustangs, for example, where some of them are very close in their stock A/F's, and some of them run leaner. So we really like to see the datalogging done in these newer trucks especially.
Another factor we have found that is really significant in this is the tires used from the factory - even on otherwise identical vehicles, we have found that it's not just whether they are the 17" or the 18", but the fact that even among the 18" packages, there have been a number of different tire compounds used - some are more slippery than others, especially in terms of dry pavement traction. We have also seen scenarios in which 4x4's with 35" tires can light them up on the 87 octane tune, and others cannot do it on stock tires - and everything in between. But they all gain about the same amount of power, it really seems to get down to the actual tire compound.
Regarding the 1-2 part-throttle upshifts - as Crystal mentioned (she's on our staff), we raise the part-throttle 1-2 shift point in that area by a very small amount - and just like when stock, how high the engine revs before it upshifts depends on how much throttle and what kind of load the engine is under - but yes, at the exact same throttle position and load, it will rev a little bit higher, that is perfectly normal. The more throttle opening, and/or the more load (even if going up a very slight upgrade, for example), the higher the engine will rev before it upshifts.
It sounds like what is going on is perfectly normal - as long as the engine is not hanging forever at one set rpm without upshifting on flat ground, the higher upshift point is doing exactly what it's supposed to do - try experimenting with using less and more throttle, and you'll see the variance in the part-throttle upshift points. One last very important point is that it does like to breathe - so with that Air Force One intake on there, it will also gain rpms significantly quicker on part-throttle in 1st gear than it did before - so that, coupled with the slightly higher upshift points being commanded, is most likely why you are seeing what you are.
I hope that info helps, thanks again for your post & have fun!

Mike,
Thanks for the info, you got the right guy i just hadn't bothered to update my profile before today...anyway thanks, i will do the data logging and touch base with you then.
