I just bought an 05 duramax.
 

What do i need to know about it? I'm new to diesel but i love it!

Well first off what are your plans for it?

X2

its gonna be my toy hauler. i need lots of torque and power

the Duramax is a great engine, LLYs and LBZs where good years

first things first - upgrade the ins & outs, get a higher flowing intake, fix the restricting mouth piece with an LBZ or Kodak one, and a 4+ inch exhaust. ether turbo back (best) down pipe back (good) or cat back (ok) exhaust

sweet thats why i bought an 05

whats the best tuning system for it?

EFI live will make you poop your pants.

And then your tranny will limp.:tttt:

how so?

unless you drive with out clothes...

no, EFI Live is the best in terms of customization. light HP increase, tow tunes, high HP, race tunes, etc

what ever you want EFI Live can probably do

That's what I'm hearing. sounds like that's what I'm getting!:tu:

Keep in mind the stock trans can only handle 100 hp more than stock. Otherwise, you'll be buying a new one pretty quickly!

Thats good to know! thanks man

that's 100hp on a good day, many don't make it that far a few do.

after your intake, exhaust, egr blocker, EFI Live & gauges, i would upgrade the transmission next

like a torque converter or?

so far my 06 is holding a 100hp tune without limping, but it's also an edge evo tune so.....

Bingo :c: You'll be good with this

right on thanks guys!

ok now i put a k&n intake and filter on my stock 05 lly and now i have intermittent power loss! some times i hit the gas and shes all there other time i punch it and its like im towing my house! do i need a tuner for the intake!?!

take out the k&n and put a factory filter in...

it finally through a light and it was the mass airflow sensor. i unplugged it and got the power back.

K&Ns can get the MAF sensor contaminated with oil. try cleaning the MAF sensor. i run a K&N and haven't had the issue but have heard of plenty that do

ya thats what i was thinking too. tomorrow im getting a can of mas cleaner

ditch the K&N and get an S&B intake, you'll be much happier:yeah:

X2 on gettin rid of the K&N. The factory ones flow great! You just need to change the mouth piece :tu:

well i cleaned the sensor up and it works great now thanks guys:jump:
