Gear woes...

Dear brain trust,

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

Custom tunes will make it more responsive and give you some more power. Do you tow with it? If so what and how often. I know bill can make the tune with more low end torque and power, this should help.

Seele: What kind of affect did the 4.56's have on your fuel economy........on average? Did it really drop off?

No I really don't tow that often. 3 or 4 times a year, a car trailer 20 miles or less and the occasional ice house about the same distance is all I'll tow. That was why I wondered if the gears would be worth it at this point. Plus the programmer seems to be a bit easier to conceal from the stealerships. Well maybe I'll do a little spit ballin' and pull the trigger on the Gryphon in a week or two.

Not really a differance at all. In town I average anywhere between 14.5-15.5, and I have had it almost to 19 on the highway taking a trip up I95. I only did it to compensate for the 35's. The real differance is in my speedo which is waaaaaay off! LOL. Soon as I get my Gryphon back that will be straight. I'll keep you posted on the economy after the tunes show up.

Check the link out below...there's a couple of formulas you can use to determine the correct gear ratio and the RPM range for your tire size.

agreed...........and the gears will be great but only go with them if and when you feel you need them. All depends on your budget
