Well, I dont guess I worded my question right. I do not want to hear it while accelerating...as in I want to get better fuel economy by when it whistles to let off some. I dont want to use the turbo unless i absolutely need it. So i want a louder sound so I know how much fuel to give it and how much i need to let off.

But thanks for the "help". I know a lot more then I do now I guess.

That still doesn't make sense. You can't base turbo sound off of fuel economy. My old 66 would scream when I accelerated slowly and I would still read 0 psi on the gauge.

You're going about this all wrong. Just get efi live and put it on an economy tune for fuel mileage. Then drive like a little old lady. That should work for what you want.

Your best fuel mileage gauge is your pyro. Low pyro numbers is low fuel consumption. You can get excellent mileage with turbo whine or no turbo sound. You can't get excellent mileage at 1200°F EGT's.

Isn't the turbo what helps theses trucks get better fuel economy?? Especially while under load? I am confused:baby:

It takes fuel to make boost. The more boost you make the more fuel it takes to make that boost. Low boost numbers while cruising = less fuel needed = lower egts = better fuel mileage.

This guy^^ lol Thank you, That is what I thought. But This is the first Duramax I've owned. I've had 6.5's for years and if I didn't hear the turbo I got 30mpg all day long with a 5 speed.

If I'm cruising at 65 mph on my economy tune, I'm running roughly 2 lbs boost. If I'm in any of my other tunes at 65 mph it's around 7-8 lbs boost.

I have a very hard time understanding exactly what it is you are trying to say.

High sulphur fuel will give you that sweet turbo whine you want, and don't let anyone fool you
high sulphur is high horse fuel, pin it to win it
it blows more smoke too so when you blow those dodge doors off and your smokin tough, they'll know you really gots tha powa
