Throttle response?!?!

I guess what I was trying to say was that the TB needs other things to make it work better than just a tune and a cai.
The gryphon will give you truck some more power and so will the cai. The gryphon and cai do this together.
In order to get the bigger TB to make more power you will need an intake, cams, and possibly injectors.
Forced air is the way I would go if I had big pockets.

I have an 02 4.6L and did notice some power gain but it could be because i also have a flowmaster cat back which allows a little better flow. The gryphon will tune your truck for the extra air amount coming in so it can put in more gas, more air+more gas= more fun

I like the more fun part but I really don't like the more gas I'll be using. I think I'll keek the stock intake and TB and sell off the aftermarket parts. I'm hearing good things about pulleys so I'm going to add those.

Just so there is no confusion. Intakes in my world are the part that bolts to the heads. Other people call them intake manifolds.
Now Cold Air Intakes that come before the TB, I and others just call them cai.

I am 100% sure I got a gas mileage boost from doing the "gotts" style mod to the stock intake. I can't really explain why this should be except that possibly I get a better A/F mixture at near WOT which in turn gives me better power shortening the time I have to be in that state?

Anyway, I know before the intake mod, I could get 15.5 mpg at 55-60 mph. Anything faster and the mileage dropped. Now I get 15.5 at 70-75, and am above 16.0 at 55-60.

depends on how you drive, it only will pull in more gas if you're on wot otherwise i believe people are claiming higher gas mileage due to changing standard shift points and that good stuff

I didn't see if it was mentioned, but one thing that is a common problem is a moderately lean condition caused by using a CAI in conjunction with Programmer that wasn't set up for the inherent lean condition the CAI will normally cause. This results in poor throttle response and poor low RPM power. The canned tuning on the Gryphon will likely cause the same problems until you go with some custom tuning.

I wasn't going to mention the "blanket response" for the cai being lean due to the year of vehicle. But it most definately could be possible. The other thing is a "small" vacuum leak.

To the OP does the idle dip when brakes applied?

Bill, I'm glad you responded. Thanks! I've heard before about the CAI/Programmer combo not working well. I have little low end/low RPM power. Power in the middle and higher RPM range is good for the 4.6L except the lag when it downshifts for passing.

Questions...I'm going to purchase the Gryphon but I'd like to know what would be best with a custom tune for my '02 4.6L. A Gotts intake mod or the Airaid intake I currently have installed? I live in HOT Southern California so I don't know if that makes a difference with your tunes. Stock TB or a BBK 75mm TB that I also currently have (not installed)? I'm also installing underdrive pulleys before I input to tune so also consider that.
