t-lok for 06 V6 and tuner
 

I'm looking to put in a t-lok for my 06 V6. As of now I'm looking at the Ford Racing 7.5" limited slip differential. Does anyone know of anything better? Also, do I have to tune with that to correct the speedo? I know you do for gears but I'm just checkin for the t-lok.

yeah... why don't you spend the exact same amount of money and buy a take-out 8.8 from a 05+ GT. Then you'll have an 8.8, posi and possibly better gears. Check out mpsautosalvage.com and speedconcepts.net for axles.

speedconcepts.com has them super cheap, but they are 3.31 gears
hillbankmotorsports.com sells one that is more expensive, but has the 3.55
