Installed Vrtuned Box..... Wow... But Lost Crackles And Bangs
Hey guys finally installed my vrtuned box.
Install was pretty easy with all the help from the members here (thanx again) and looking on YouTube.
Huge difference in power and it seemed to get stronger as I drove the car, which makes sense after reading the c450 forum install with the dyno showing the same.
Now the bad news... I lost the crackles and bangs, I have read on the forums that this sometimes happens right after install but returns after a few weeks.
Has anybody lost the crackles and bangs permanently after installing a tune?
Not saying I am taking it off but damn I lost all the goodness of the PE exhaust.

Thanx
When you saw lost, you mean you lost all of it? Or is it just reduced? Does not sound right. But then again your VR tune manipulates the fuelling, so it changes the fuel trim, which in turn can mess up the PE sound. Just a speculation. See if it comes back and report back haha!

There where a few here and there and when they did go off they where extremely muffled.
Keep in mind I have asr module so my flaps are wide open, I think If exhaust was stock you would barely beable to hear them at all.
Yeah I agree I did have to connect tune to fuel so you are probly right it is messing with the overrun.
I will keep you guys posted hoping it comes back.
I can only wonder how JB1 feels cause I feel it makes way more power than my tune.
BTW it might just be me or the fact I didn't install engine Cover right away but did u guys here more turbo whistle and blowoff Valve noises after installing tune?

Eh, um not really no. May be its in your head. But if you absolutely want to be sure, May be a checked the intercooler pipe to the intake? Star4life had the same problem here. Shoot him a message if you can. Just take a look at this. If this pipe looks good it might be in your head. Secondarily, look at the boost gauge in your AMG cluster. If you are not getting full boost, or getting full boost and then it drops off steeply, you might have a boost leak too.

Pretty easy to diagnose.

O no it is not anything like that what I mean is I can hear the turbo spooling up.
I drove around looking at those gages you told me about and monitored the check engine light and so far all is running great.
Now I am already getting greedy about turning the tune up. On the bottom of unit I can adjust tune from setting one to setting 9. It is on setting 6 now. I am running 93 octane at sea level so maybe I can turn it up one or 2 more clicks.
According to what I have read setting 9 is for 98ron which is basically 94 octane in states.
I was hearing a lot of turbo noise on my 43. Took it to the dealership and sure enough I had a boost leak. On my gauge cluster, my boost would max out and then slowly fall to 3/4.

Just an update I finally turned the tune up to its highest setting of 9.
I was originally running it on a setting of 6 with summer weather but now with the cooler weather the car is running better.
The power increase is very very noticeable, I mean the torque increase is massive. In lower gears the car feels like it is going to take off! The front end lurches into the air when I get on it in first or second gear.

Can't wait for my intake next week!
Get a dragy then you would be able to get a sense of the numbers.
