i like the Hiss tune for the instant spool up and low end torque, but i notice that the 6.6.43 tune runs and shifts smoother. I like the hiss tune just because you know its a Duramax coming around the corner.

Vacum??? Mine sound like a Jet going full afterburner. :gearjamin Rumble is so boring. Got 3 Duramax's and 2 Cummins on my block and they all sound the same "Blub Blub Blub"

I've heard the rumble tune makes the horrid throttle response even worse. How could it possibly be worse. :rofl

Same here please. I'd like to have the hiss tune to compare the throttle response and turbo spool with the latest tune.

I prefer the sound of a truck as opposed to the sound of an industrial vacuum.:cool:
Like the rumble myself as well ken, at wot when that stocker opens up it sounds like an afterburner on a f16.
As far as throttle response with the tuning coming out I think people will enjoy both worlds.....

If someone has the file to send to me then I'll host it for anyone to download... PM me if you do... Thanks.. Just trying to help everyone out... Why doesn't H&S keep them on there site for ppl to download? You would think they would want you to have options on which update you like the best and run it....
