I have a 2012 6.7 with the basic stuff done. S&b intake, 4" downpipe back, fully ******d, cold and hot side pipes, sct livewire with tyrant tunes. Midwest diesel transmission, 12" lift on 40's.

Thinking about gears to get some acceleration back from the 40's. What mods should I consider next? Injectors and lift pump? Bigger turbo and studs?

Thanks for any input guys!

Get a larger drop in vgt turbo and either a 15+ fuel pump or dual fueler.

I would for sure do gears first, it will be your biggest drivability upgrade by a long shot.

Depends on what you want for a power goal, if you don't plan on going nuts, I would do a 15+ pump and a MPD budget kit with a 363sxe. Anything bigger would be a total waste with just a 15+ fuel pump. Honestly a 362 would still max a 15 pump.

Thanks for all the input guys. Doing 4.10 years first then probably swapping turbos and the duel fuelers. The 4.10's with the 40's will give me a effective gear ratio of around 3.40 or so I believe. Trying to stay close to the factory gearing of 3.07.

There's no such thing as 3.07 factory gears. 3.31 or 3.55 is what you had.

Well then the site I looked my axle code up lied cause that was what was listed. Guess I'll have to try again. Do you happen to know what the codes are?
