Making a video explaining the choice between a whistle

and a growl was an ideal scenario for the Blessed

Performance team based on website traffic, and

that traffics engagement, as well as the troubleshooting via

email and, or phone call that might of occurred, and

inevitably will continue as our favorite trucks popularity grows. 

We promise you there was many upon many prior to finalizing

the thought of this video's worthwhile, Timeless content

indeed, like this blog is worth the read: we are about to

break this down in a timeless and traditional fashion, because

call us crazy, but we believe that 6.0L Owners, and Enthusiast alike,

love to learn, if you love to learn, then naturally you love to read, however in some case with truck folks, the learning is done by a hands on trial and error journey. This can help those folks too, all they need to do is take the time. 

Let's get started with the fact that if you own a 6.0L or your simply an automotive student of any sort looking to learn more about the engines wonders, rumors, respected owners, and or dreadful issues you will be forced to overcome. And if your a new owner, no worries.

 We are truly American made, from boot strap methods of old fashioned nature in hard work, accountability, and loyalty to any of the product lines we offer on our website, or at our warehouses across the the USA.  

While swapping out the KC 13 Blade Turbo for a KC Stage 1 Gen 2 10 Blade Jet Fire in Silver Bullet the 2007 6.OL Powerstroke, a golden opportunity for learning presented itself in both blog and video format. You can actually watch below after reading this: or vice versa, our YouTube feature of in which this blog is based upon.  

Remember that VGT Duty Cycle is "Commanded" in your

device monitor options. Don't forget that you don't have a

vane position sensor: so you can only see commanded,

you can't see what all the Turbo is doing too. So when it's

commanding .15 that means: The vanes are opened up as

much as possible, and you should have more of a rumble

tone to it, sort of like a lions roar.

Now if it's commanding .85 that means the vanes are closed at idle, and it will have more of a whistle, a lot folks reference the sound of the 13 blade to comparable with a vacuum, jet, and simply neighborhood pisser offer.

Realistically speaking: like Matt will often reference is his

Diesel Ted Talks like so, your not deciding on anything that will show performance gains robustly.  

However when choosing one or the other it should be noted.

Your going to

inevitably spool faster with the Closed Whistle option,

because the vanes are already closed, so that's a plus for

some, it will result in a very minimal improved throttle

response. 

Growl is going to result in a more smokey scenery,

and this again, something some owners are looking for while

others avoid it. It's up to YOU, that's the beauty in the ability to

choose your trucks sound, is it not? The point of us doing

video's and blogging about this is to help you get a hold of

the facts before your final decision is made, so you can

know what to expect before you even get your project

done.

If you have Tow Tunes: It's worth also considering that in this

video Matt can be quoted as saying "I don't really

recommend the growl on any town tunes, and here's

why".... 

In the Tow Tunes we forced the vanes closed as an

exhaust brake, obviously not a true exhaust brake, however

even a couple extra PSI exhaust brake can do wonders

when towing a heavy load down a mountain. 

If you go with the Whistle on a tow tune, and your coming to a

stop, the exhaust brake will never stop. It will go all way down

to 700 RPM, Which is you sitting at a stop light.

So Matt recommends the Whistle on the Tow Tunes, as well as the Race Tunes. 

He says on the Xtreme, he's going growl all

day, because it's a fun tune for that reason.

 keep that in mind. 

It's not a make or break decision just

because Matt says to consider this, it's simply Matt 

letting consumers know what He see's, because we get

countless calls, and emails on a daily basis asking for his

opinion, and there is good reason for that. 

Keep in mind

this is all about IDLE, only at idle will this decision play a

huge role, because it's sound based. 

If you have Whistle, and feel like your not getting the right

sound, we strongly suggest cleaning out your EBP Sensor

(Exhaust Back Pressure Sensor) before calling in for us to

troubleshoot with you, because it's most  likely clogged, if you call us

first that's what we will tell you to do, before further

testing. However keep in mind fixing a truck through a

phone call can be difficult pending on the person on the

other ends understanding of things.
