Oh okay, perfect. What is the new temps now reading? Lower than before upgrade on IAT2? Glad to hear it got figured out a bit.

The only real way to tell if a specific addition added HO or TQ, is to test each one on a dyno WITHOUT changing anything else. This said, things get complicated when multiple items are added. Nonetheless, the bottom line is often greater than the sum of the parts! Example...
I can tell you everything I have done to my 5G (tuning, CAI, exhaust, turbo tubes, & intercooler). If I add the numbers (HP & TQ) each addition added (according to the makers of each part added), I'd fall short by nearly 25%. In other words, just adding an exhaust might add say 5 HP, and the CAI another 3 HP, adding them both may add up to 10 HP (only an example as I didn't make that many dyno runs). And...
Besides the Ford Performance tune, the single item which made the most difference, was replacing the turbo tubing. Adding the intercooler after the fact, wasn't noticeable in the seat of my pants, and barely seen on the dyno numbers.

I just got home from work and have not changed to the iat2. I will shortly and let you know. Probably tomorrow

Out of everything I have done so far it seems the damper has made the biggest difference so far. The tune, intake, intercooler, intercooler pipes, downpipe and muffler may have helped, but none of that matters without the tailgate damper?

Which turbo tubing did you go with?

Mishimoto. I was going to use their intercooler too, but the piping connections don't match up. The one I ended up using, is a custom from a local Honda-esque speed shop. Cheaper too.

So switched to IAT2. Temps now about 10 degrees higher from air temp. Unfortunately it’s 90 in West Virginia today?

There is another factor related to the temperature.
Gasoline refiners often change the Reid Vapor Pressure (RVP) to match the seasonal environmental conditions, as required by the EPA (CAA standards). While this does not effect the incoming air temperature, it indeed changes what goes on during combustion. Hence the incorrect RVP for the ambient will effect engine performance.

Doesn't the ECU have some sort of reference table for timing/load based on a combination of factors like IAT? If the AFE intake improved air flow but the sensor tells the ECU that the temp has increased by 30 over ambient, would it not provide the ECU with bad data? I wonder why they moved the sensor.
FWIW, I had an open air filter element (a "hot air intake") on a car with a similar setup as the ranger and still only saw IATs a few above ambient.

There is more here than meets the eye. One issue drivetrain engineers consider is heat soak. If the air intake were make of aluminum instead of plastic... Well, you get the idea. We assume, therefore, that Roush et. el. have also considered heat soak into their selected location for the temperature sensor? But have they?
The procedure used to measure the temperature is also important. Was the vehicle sitting still in our driveway? Or, traveling 45 MPH down the highway? I suspect these two conditions also vary depending which CAI we're comparing to stock.
It further pays to remember, that most of us are not driveline engineers, and our testing parameters aren't like theirs either.
As the Bard once said... Much to do about nothing!

I was going to log IAT2 temps with the Velossa Big Mouth before and after but I figure controlling for all the variables is more than I care to do. Just going to enjoy the ride and see what the butt feels, probably wont be anything at all. I am sure the temps decrease by a couple degrees though... We shall see.. either way, it really doesn't matter too many damn things to consider like @Apples is saying.

Rangers from the mid 90's and Beyond have CAI from the factory. Dumping a aftermarket with a open design will just suck the air from the engine Bay. No go. you need a another intake point out side of the Truck or Just use a High flow Filter. Most CAI do not do what people think they do and can be worse for the motor.
