6.7L Cummins Forum

Hi all,this is my first post.

HELP! My truck is at the dealer for MIL #2262 (turbo boost) & #0409 (EGR) problems.
I currently have TSB 18-013-008 (p/n #62350430AS) that was downloaded in June 2009 due to the above MIL #s and also downloaded the anti bootloader program as well.
I am more than a little wary of another download which killed 2 mpg, made my exhaust brake less powerful and prevented me from modifying my engine/exhaust.
Does anyone know exactly what changes are made to the ECM when the J35 (TSB 18-024-009) recall/reflash is performed?
I've read everything I can find about the J35 recall, yet no one seems to know exactly what modifications are made to the ECM programming.
"It improves power and mileage." "It runs worse and cost fuel economy", are just a couple of things I have read about the recall.
Lastly and most important will I be able to use a Smarty 67me with this recall? I plan to lose the DPF/egr and increase my mileage.

ps.
My dealer tells me
It void my warranty
if I don't do the J35
Thank You,
Puck '08 2500 4x4 manual
