Default 2008 DMAX mods

Does anyone have any opinions on the Edge Attitude set up or ATS diesel stuff? What is the best aftermarket tuner/box ? Need help with mods. Any recomendations on air boxes, exhaust would be very helpful.
Thanks

Get in touch with a custom diesel tuner, they can give you much better results then a regular programmer.

If your not comfy with tuning yourself, PPE makes the best canned tunes, but you will need trans work. I suggest at very least putting the Transgo Jr kit in your ally, it will raise line PSI for better holding power and crisp shifts. i have the EDGE juice/att on my truck, im one of few that havent had many probs, i Love the adjustability and the smoke on level 6. You will also want a lift pump with a hot tune. Your stock airbox will be fine with the PPE free mods, Dont waste your money on a cold air intake. MBRP makes a great exhaust for these trucks.

powerchoke who? Cummings what? im sure there out there but around here no problems on the street, Im not saying i have the baddest truck but DAMN, this thing is faast for a big pig. I need to get a bigger tune ( PPE or EFI live) But the Edge had enough TQ to bend my tie rods with sleeves and my Centerlink doing a boosted launch at the strip, so no ET's yet, but i'll be doing some suspension work this winter. PPE and my current combo WILL produce 12 sec time slips.
