Hello my name is Jason, I have a 2004 Duramax LB7, straight piped and ppe tuner are my only mods. It has been a great truck but hopefully I can do more mods, just trying not to go broke doing it. I have had this truck for two and a half years and it has 134xxx miles and many more to come.
Your D-Max is capable of allot more! Just need to work out some of the bugs that happen when modding it. The transmission is the big ticket for strengthening. the allison Transmission has software that eats itself when applying the heavier tunes from the PPE.
