No way 12's without nitrous. That motor running "all motor" will go low 14's high 13's now that i know its flywhell hp and not rwhp. Yea the pois will help and so will the 3.73's for sure but...theres no way that tuck will hit 12's unless its got a shot on it lol. ((no offence to the owner)) Sounds like a SWEET! truck.
You better run it soon i wnna see some times man!
