Still have that trani lag.

Andddd now I'm going to totally ruin the quality of the coversation here...

I've got a 06' 5.4L 4x4 with the 3.55LS, and now it's got 275/60/20R cooper zeons to deal with (32.99") which has robbed it of a decent amount of performance. I've been searching for a few days now on this forum and other f150 forums for what my best option would be. So far the vast majority of responses I've gotten have reccomended I buy a grypon (which I've been considering already) and rolling the dice on my extended warranty of 5 yrs 75k (I'm at 25k). Only two people have suggested regearing and my Ford dealer basically thought I was a mental case for asking them if they could install them for me. I've accepted the fact that my knowledge on this subject is severely lacking. I'm not a total lead foot, but I do enjoy performance. I work with one of your customers (glockwinger) and he giggled like a school kid when he got his custom tunes. I'm intrigued...

Is your Gryphon the answer? Or should I be looking at new gears? Or both?

Thanks, Aaron

I'd say just go with Gryphon first. That may completely satisfy you........but if not, then I'd throw some deeper gears in it.

With your new tires you now have an effective ratio of 3.34. You would technically need a 3.76 ratio just to get back to the feel of stock. So purchasing 3.73's won't even quite get you there. You would want 4.10's or 4.56's if you decide to do gears as well. That's my opinion anyway
BTW - Don't worry about the Ford dealer looking at you funny!
