intake, exhaust and efi is all you need. duramaxtuner.com is my recommendation. stock transmission safe tuning.

i also recommend full synthetic oil. i am an amsoil dealer. change my oil once a year. get between 15-20k on it. full drivetrain change can help mileage.

duramaxtuner doesn't have the greatest reviews on duramax forums. I'd suggest http://dansdieselperformance.com
don't care what the forums say. i speak from experience. but if you want dan to tune your truck go right ahead.

I'm also in with a vote for duramaxtuner My buddy had his 03 tuned couple years ago he's acually the reason Tyler switched to efi live Brandon and tyler were both at the strip with us. bone stock truck with dmaxtuners tunes pulled hard don't remember the times but i'll be getting my truck tuned by him. his trans isn't messed up any worse than it was with his edge
i've had stock trans tuned efi on my truck for over 2 years now. never once limped my trans. my stage 5 tune put down over 400 hp and 800 lbs of torque at huckstorf. i limped my trans a few times with my ppe but since having it efi tuned it's never run better.
