Custom Tune Question

[Carolinaboy]

Ok so I've just joined here I don't know if this is the right spot to post this question or not, but here it goes. I have a 2004 F150 FX4 Screw. I have a gryphon and that's the only performance upgrade I have. I am going to be running true dual 18" Dynomax Bullets 45'd out the back here soon. Then upgrading to AEM Brute force or S&B CAI.

SO my question is how do I go about getting a custom tune? I do 80% road driving and occasionally go off roading when hunting or shooting out in the fields. So most likely I would do a 87 performance tune, I've heard great things about that. So what do I need to do ?

Thanks in advace
