What's the fastest bone stock 5 speed times in the 1/4? Been busting off pretty good times recently with my 275k lb7. 13.3s and 13.2s at over 100mph. Trans will limp very easily at lower rpms so I have adjusted the tcm for shift points and ecm for defuel and trying to get away from torque, ect as we all know that's what will kill an stock allison. Anyways took the old ranch truck to the track friday night and busted off a [email protected] with a 1.87 60' (front Is leveled) truck weighs 7200lbs also. So im wondering who else out there has made there 5 speeds live through abuse. I'll post up a pic of the truck and time slip.
