Allen retuned mine for my 80 swap and everything works great. I have had it for at least six months. The only thing I suggest if you are doing it is get some 4.10's if you dont have them. The 3.73's I have are killing me out of the hole and draging my gears out forever.

 

Hmmm. Maybe ill have to talk to allen about tuning for my 4L80. Does he charge his full price just to reprogram for the 4L80 or is there a discounted price?

 

These kits dont come included with a converter. And yes you can order everything seperately.
