Should i get rid of DOD I am going to be having a tune dune by MonteSS8707 on Sunday, One idea ive been toying with is tuning out DOD. Ive heard mixed reviews to this. The negative side would be the loss of gas mileage. The plus sides would be less wear on the dod specific parts, and no more of the awful "helicopter" sound. I wouldnt mind getting rid of this but i would like your opinions first.

I personally don't feel DoD hurts the vehicles or causes any uneven wear, but that's just me.
What you have to do is ask yourself what you expect from the car and how you use it. For example I drove 527 miles to see my family, so the DoD was nice on the highway. I was getting 29 mpg as opposed to say 16 or 17 w/o DoD on. So that saved me a good chunk of change. On the other hand driving around Ann Arbor the DoD never gets a chance to click on, so it is worthless.
So where do you drive? Do you get a lot of benefit from the DoD due to highway driving, or are you more of a urban driver where the DoD isn't as useful? Assuming you see DoD click on a lot keep in mind reducing your fuel econ by 33% (more importantly, think of it this way, if you fill your tank 3 times every two weeks, you will now be filling it 4 times ever two weeks)? What else could you use that money for?
In the end I see no huge perfomance benefit to turning DoD off, it takes the vehicle .25 seconds to exit DoD mode. If I'm going to race I just rev the car a little right before I race and that rev clicks DoD off, and I'm good to go.
Your car, your call man.

I could not stand all the rattles and stuff so I got rid of it......i still get 26-28mpg on the highway....and right now with mostly city driving I am at 18.5 and I remote start the car every morning to warm up...it stays on till it shuts off.

ow, I must have a factory freak or something, because I never hear a rattle in DoD. Either that or the fact that my bass is at +6 and I listen to rap music must mean that my sound system is covering up my rattle (not to mention the hearing damage it likely causes). I'll have to turn my music off never time I'm on the freeway and see if I can hear and/or feel anything without the bass pounding away.

Well the thing is it isnt DOD really that causes the rattle, i think its a wide open exhaust that i think it the culprit, when it goes into 4 cylinder mode its like riding down the highway with just the rear windows open. The parts listed are what i used on my exhaust and will give you an idea why, it is much louder that the magnaflow cat-back system. So i guess what im talking about really isnt a rattle, more of just an annoying exhaust sound. But i do love the way it sounds in v8 mode

I would suggest to leave it on because there is no performance to be gained by removing it. You are up on the highway quite a bit from what u say so I'd keep it. I know how annoying the helicopter sound is and so does my fiance. But if it saves some gas, hell its worth it to me. More money for other mods or more gas to burn. I'd keep it, I've still got it on mine. But its whatever you want to do.

What MonteSS said
I feel the "vibration" at times in 4 cyl mode. perfectly normal when your exhaust is open or altered. Ahhhh the sacrafices we make! Buts its not anything thats annoying to me! So yeah I'll Keep it my friend,......

From someone who has actual experience w/ and w/o DOD. Go ahead and disable it. Most of my driving is city and I actually saw a slight improvement in MPG.
I think Lew saw an improvement also, w/o DOD.

EXACTLY this is what the guys are talking about when they are referring to rattle, Helicoptor, or vibration. It sounds very choppy in 4 cyl mode but only if you have some open exhaust, flows, flowmasters, deleted resy's, etc!

tune it out. i tuned mine out and never looked back. and my car averages over 19mpg and i drive mostly around town. the way i see it u didnt buy a 4cyl car, u bought a v8. and i dont know about u but i didnt buy a full-size v8 sedan for fuel economy anyway. if thats what u want buy a camry hybrid or something. just my 2 cents.
