I ran a ppe hot race on level 2 for 5 months no problems today my truck would not go over 2000 rpms.It was shifting hard.I went back to stock n truck is runing fine.if i keep runing without the dpf delete could i damage somthing?:help

your saying the tuner does not have a dpf delete but you have your dpf removed?? if so then ya its gunna throw codes that wont let you drive it normally!

 

[aggietb]

oh nevermind your saying you removed the tune so you have it stock without the dpf, it will just throw codes, i dunno exactly what it will limit you to, but it will. could have you possibly limped your tranny? did you read the codes?

No codes came up.What does a limped tranny do???

it will throw codes 2k rpm sounds like fuel or tranny limp when was the last spin on ally filter change and also you prolly need to change your fuel filter....where you hard on it alot while it was programed
