Hi everyone, I have a 2015 c300 sedan 4matic
It has the following performance mods
-Custom exhaust (straight piped from catback planning to add valved mufflers later)
-amr catless downpipe
-custom ECU tune stage 2 (by local tuner)
-custom TCU tune stage 2 (by local tuner)
-bms intake
-weistec BOV
-tornado tuning solutions big intercooler
So my car has a decent burble tune on it, see attached videos. However, my car does not pop/burble in park and has a rev-limiter set about 4000 rpm. I am happy with the rev limiter as obviously, it was put there for a reason so 18 year old me doesn't send piston #3 to antartica, however i am extremely unhappy that my car for some reason refuses to burble (or pop) in park. Me and my tuner are very frustrated as we cannot find any solutions to this problem. if anyone has any solutions, of course please let me know. And no, I will not be changing my tune to any other brand/tuner sorry but thx my c300 currently on h&r springs on some enkei rejin 19's
hx.
Thanks man, stage 2 with all listed mods the car makes a little over 300whp.
Pretty good and fun compared to the lackluster stock performance.
planning on purchasing the upgraded turbo kit from webuildturbos and that will see adleast 400whp.
The turbo blow off is not what causes burbles.
Idk the direct science behind it but i believe the turbo blow off valve is just releasing the pressure from the turbo itself.
tuning is what allows the car to burble because it provides the ability to store unburned fuel in the exhaust that causes the actual popping itself,
and yes the turbo does spool in park, when i rev it up to the limiter and let off i can hear it spooling while in park.
That is some serious power gains your getting!!
I was not sure but figured someone would, only reason I says that was I barely hear my intake/turbo noises in park, only when I’m in gear
haha yes the power gains are definetly great. As it is right now a fully stock c43 only starts to lose me when we pass about 60mph considering he doesn't use launch control at a red light.
Natually intake/turbo noises in park would be less loud because there is less active air going through the intake system as the car isn't moving.
one weird thing i noticed is that all AMR tunes have the ability to be annoying (pop, burble, noises) in park so i might call them and ask how they were able to achieve that.
My car would kill yours for sure.. but I see allot of C300 owner running pass me and I just let them do that. I already know how fast me car is just like how the C63 owners find out fast. I had some guy trying to pass me in a C63s and he found out right away but he could not do that easy. Now, I know the newer cars are going to be even faster until I upgrade to a newer car when I think it's time. My car only burbles or pops when I hit it in not matter which stat the car is in but of course in S+ it burbles like crazy and pops just the same which if you are behind my car, it hurts your eyes. I keep thinking that I'm gonna stop modding but I'm getting to the point.
This one time, I was sitting at a red light next to a Lamborghini Aventador. When the light turned green, I nailed it. I looked in my rear-view mirror and the Lamborghini was way back there. My car is faster than an Aventador.
So, you may be thinking the same thing I am... this doesn't mean s**t.
