I have a 95 F-150 4x4 5.0 with the following mods:
Ford Racing E303 cam
GT-40Ps
24# Injectors
K&N FIPK
Edelbrock Truck Performer intake
Ford Racing shorty headers
2 1/2 inch S/S exhaust out to 3 inch chrome tips (Yes, it is obnoxious loud)
March 1000 underdrive kit
Permacool electric fans.
The truck is factory Mass air.
I'm going to upgrade to the 61 mm BBK throttle body and Scorpion 1.7 roller rockers.
I want to upgrade to the Ford racing 90mm MAF housing for the 02 lighning.
Will the sensor in my 95 Eddie fit in it?
Should I go with the 71mm Vortec housing instead?
Larger TB and 1.7 rockers are a waste, the stock 52mm TB will support 400+hp and you're nowhere close to that, and GTP heads stop increasing airflow at 0.500" lift so 1.7 rockers won't do anything but increase valvatrain stress. Your truck needs a tune more than anything, you have already got WAY more stuff on it than the stock tune can handle.
You'd benefit more from a dyno tune. They can do idle, part and wide open throttle tuning. Assuming you have a automatic transmission, they can also change the shift points, shift firmness and converter lock up schedules.
I would like to get a dyno tune, unfortunately, I don't have access to a dyno facility. Please forgive my ignorance, can't you get close with a virtual dyno and a laptop tuner?

If you are comfortable and understand how to tune a vehicle, you can also do this yourself. There are several software programs available, that “Speak Common English” that will allow you to tune your vehicles ECM. One company is HP Tuners, they have a website….they offer two core programs, one for those who are doing dyno tuning and one for the home-garage mechanic (which is priced at about the same as most of the “canned tunes on the market) …this version limits the span of adjustments as a safeguard against doing something outside of the oem scope……basically, keeps you from doing something “too stupid by accident” (grin).

It's kinda like taking your car to "Tune-Masters" in the 70's...a cheap tune-up...
Especially with the upgrades you have..and obviously you understand basic engine tuning, this is something you can easily do and evaluate/adjust yourself based upon how the vehicle drives/local environmenatal-gasoline conditions and more importantly, how you want it to drive.

In my opinion, there are some cases where you can, and you will notice an improvement. If not, you have to mail the chip back to the tuner, have them change values, and then they mail it back to you hoping that it will fix your issues. The reason this becomes a challenge is because the tuner doesn't benefit having the hard engine data to work from. I've been doing my own tuning for many years and I can tell you that this engine data is critical (not just WOT) to tune a motor properly, with aftermarket parts.
I've never used Quaterhorse, but I do have a copy of CalEdit (Tweecer) on my pc. I use SCT Pro Racer tuning software, (with a datalogger), on my truck and found it to be much more user friendly than Tweecer. The guys I know of using QH speak very highly of it, so it should work well to dial in you combo.
