have a 08 6.4 crew cab short bed, cold air, sct on trans only, dpf delete, it will run atleast 80 and not shift into the last gear, should i try to put it on a different tune to see if that helps or just plan on a new trans.?

 

Those 6.4 TRANNY are tough & can handle more HP & TQ

 

i'm just scared to blow it up, no truck no money makin goes on ha

 

Remember your truck is under warranty !!!

 

not with the dpf delete, but i guess throwing it back on would be worth the 5 grand for a new transmission

 

if you do get a trans your truck will be a new monster, trust me. been there, done that, will never go back to a stock trans 6.4, i refuse to drive my dads

trying to fund my suncoast build.. but for you i would say your just fine with a stocker...600rwhp capaible all day long no problem

 

soooo, the stock SCT tunes gotta go, i barley beat a benz that my 6.0 walked all over

 

IDP imho

 

i'm gonna try them and then some RCD and see which i like better
