Heat being sucked into the CAI. (JLT II Issues)

You are correct, I changed the title to reflect the real issue,
After posting it went a different way... Sorry...
All CAI Heat Shields can allow heat to be drawn up into the intake
This has nothing to do with the JLT II Intake......I am Very Happy with my JLT II (I Love it)
I has everything to do with the Tunes and CMDP

You're blocking the "heat" coming from underneath the shield? Correct me if I'm mistaken, but isn't that where the vast majority of outside air enters? Seems to me you're only choking your engine now.
And on the CMDP thing...Ford put 'em there for nice low-end torque - to keep the intake velocity up. Taking them out is hurting you until probably 4000 RPM...either put 'em back in or launch at a higher RPM.

I have Roush UDP, but the real issue is that I have two tunes
One From SCT Tuner 1 and the other from SCT tuner 2
SCT Tuner 1's Tune I ran for a year was just for my intake.
SCT Tuner 1 is real busy and never returns my requests so I purchased a
tune from a very popular SCT Tuner 2 with the FRPP CMDP.
SCT Tuner 2's tune has an issue with the low end launch It feels like the timing is off and the car will not move until 3000 rpm. Meanwhile SCT Tuner 1 got back to me and added CMDP to my previous tune.
this tune does not experience this low end power loss. I step on the gas and the tires smoke..
So you say then why not just stick with SCT Tuner 1's tune. Well the Tune is Weak, shift points are off and my 1/4 mile time with this tune are average. 13.3-13.4 @ 104
SCT Tuner 2's Shift points are SICK !! Awsome the car is a freaking beast above 3000 rpm I think I could hit 13.1 - 13.2 with it, if I can get the the can to revv up when I hit the gas,
Tuner 1 - 60' = 1.88
Tuner 2 - 60' = 2.3 no tire spin at all the car just won't move
I do not want to list the tuners names because this is not a who's tunes are better.

Sure, every cars different and dyno numbers don't mean squat, blah blah blah, but it would be kind of difficult for it to help one car and then significantly hurt another to the point you could actually feel it, especially since so many have had good luck with them, unless there was something wrong with the tune or install.

These aren't "cold air intakes" by any means. And the heat shield isn't the best in the world. You'd think Ford would have come up with a better way to get the outside air to come into the engine bay through the fender, but apparently that is NOT the case. You'd be surprised how much air does not come up from under the car.

If you have tested this, then please post your data to support these claims.
Tons of members here have tested this, posted data as well as us at JLT.
When your moving you will see your IAT's drop fast. I just did it again this morning.
68 degrees outside and IAT's @ 55-60mph was 68-70 degrees. At 20-30 it was running 78-80 degrees IAT.
We have tested this on most all our systems and find that the 05-up GT, V6 and F-150 kits avarage 8-15 degrees above ambiant air temp @ 20-30mph and as low as 2-10 degrees above ambiant air temp.
Testing this is simple. You can use a Livewire or a laptop with the SCT software from the web site. Datalogging is the only way to know your IAT temps.
Thanks

Some one posted using a secondary 12 volt fan under the headlight forcing air torwards the intake to help reduce the idle air temps, I wonder if this helps?
I would like to reduce the idle temps when Drag Racing I think it would help the 60' times to be able to have cooler air at launch.

Spectre makes components for DIY CAIs. Including an adapter to fasten a 3" hose to the end of a conical air filter. I have visions of doing that and running the hose down into the lower grille area, as my '68 442 W30 was.
