programs for specific intake

[F150FX4]

Hi ya'll I'm new to this site. I am looking at getting a Gryphon but I was also looking to get the spectre CAI I was wondering if there is a custom tune for this intake cause it is 4" tubing as opposed to the others which are smaller any feed back would be awsome

First off.
Welcome to the forum!
Next, my opinion on CAI's.
Save yourself some cash and do the DWV/gotts mod.
OR
Do a K+N FIPK or K+N Series 77.
One of the best user/truck/tuner friendly CAI's on the market.
OR
Stick with a CAI that's going to be 3" piping. The 3" offers the optimum flow for your TB.
The 3.5"+4" have more potential to cause drone and that noise gets annoying after awhile.
JMHO

The gotts mod is only about $20 at a hardware store. It is basically a 4 or 6 inch section of a 3 inch pipe with a 3 inch flexible PVC coupling. The "gotts mod" replaces the stock snorkel in the fender well. There is a very good write up on here. This explains everything and then some...

Just to add to this, unless you've increased the diameter of the TB, it acts as a choke point for airflow and I doubt the 4" intake can give you any benefit at all. But, since the two different sized devices were not really engineered for each other, I can see lots of potential for problems, as 88Racing said.
