sorry for the late reply. you're welcome just enjoy them. a tornsen is a posi type carrier that uses gears instead of clutches to transmit power to the axles. it wasn't cheap but i'm so glad i bought it. installation was free since the gear was being changed. it is a detroit tru trac unit. it sure works nice when taking off hard with the front wheels turned. chatter is eliminated. now i have to stop the wheel hop taking off in a straight line.
It allows the engine to get into the torque peak faster and really improves the acceleration. I used to work at Holley carb years ago. Wanted to start tuning EFI like I used to tune carbs. Bought the software to get access to all the parameters. Definitely get a tuner. I go thru 5startuning.com let Mike take care of youur needs. The LiveWire is nice if u want to monitor PID's while u drive. If u don't like the cost the X3 is the way to go. Mike can do the tunes or if u want u can get the ProRacerPackage software and do it yourself. It will pay for itself after a few tunes.
I'm running stock size tires and it drives like I am not using OD. I had a tornsen carrier put in at the same time the gears went in and the front gears had to be switched also. Don't remember what it all cost.
why the 4.88s im looking to regear for my bigger tires that will also give me more power and do you like the live wire had a friend today tell me i should get one how much did your gears and install run you ..?
