after cai,catback,xcal2 w 3 custom tunes
ok heres the question ???
after cai,catback,xcal2 w 3 custom tunes.
why would you need to go further with say data logging , dyno runs??
the computer should be able to go from there with the custom tunes bringing it in line .
are you saying that the custom tunes are just like the other canned tunes ?????
and not covering the parameters ?????

Datalogging and Dyno can confirm that the tunes are running their best.
Custom tunes are always better than canned and cover every parameter available but every truck is different and it is great to verify that your tune is giving you all that you paid for and doing it safely.

True custom tuning such as that done @ Troyer actually rewrites the existing tune format within the PCM. Data logging and dyno testing are a way of verifying that the newly written tunes are acceptable to the truck modifications.

Hello fallingUP,
Sorry, but the PCM does not just somehow "magically" compensate for whatever you do on it's own - that's where your logic is wrong.
The exhaust system makes no difference, it's the intake kit - and on these newer F-150's starting with the 2004 model year (though it affects all of them), the effect is very large for any intake kit that actually adds power. It leans out the engine dramatically, sending the EGT's skyrocketing and not adding real power until the TUNING corrects it to get the A/F ratios in the ballpark.
You have no idea what an intake kit actually DOES to these vehicles until you datalog it and get the A/F ratios - and until you do THAT, you are playing with fire. Is that what you want to do with a brand new $40K vehicle? I don't think so.
Now with us and our Troyer Performance custom tuning there are certain exceptions to this need to datalog - meaning certain intake kits we have dyno'd many times and thus have transfer functions for that get the vehicle's A/F ratios so that it's safe and very close (if not spot on) to what is being commanded. Then from *there*, it's optional as to whether the vehicle owner wants to datalog and take advantage of the fact that we analyze all of that data and make any needed changes completely FREE - which, by the way, is the best bargain you will *ever* get.
The intake kits we have transfer functions for use on the 2004 & newer 5.4 3V F-150's are primarily the Air Force One units, as they are the best on the market and the most commonly found, and add the most power. We've tested the 27 or so different intake kits out there, and the AF1 does, by far, the best job overall. Now we also have transfer functions for one version of the earlier Airaid kit that still leaned out the A/F, and we also have transfer functions for the Volant intake kit (which is terrible for power, especially at higher rpms), and for the K&N FIPK kit. But your best bet is the Air Force One, as it is made out of the highest quality materials and gains the most power - and it's rare you get those 2 attributes in the same part. Being able to get mirror-polished (by hand!) T304 stainless steel in aircraft grade for basically about the same as what the plastic intake kits cost is a bargain.
The bottom line is this - go with us on this, and use either the Air Force One intake kit for the best gains, or you can go with the current version of the Airaid intake kit - we keep them both in stock - and if you do that then you will not need to datalog for us. And going with the Air Force One for the intake kit and then the Troyer tuning & the exhaust we provide, that way you get the absolute best parts money can buy in each of those 3 areas, so you get the best power & performance gains and you'll have piece of mind. This is precisely why we offer our Stage 1 kit with the parts we use, so that with the work we have already done, you do not have to datalog, it become optional.
If you have any more questions on this, please feel free to give us a call at our number listed below, and ask for me - I'm usually on another line or out a lot given all I do, but I will return your call and be happy to explain it all to you, answer any questions, etc., as I want you to have a thorough understanding on this and know what you are getting into, and feel comfortable with how it's done right, etc., OK?
I hope that info helps, & thanks for your post!
