So I just dropped my 2012 c250 coupe off for a blown center speaker and they gave me a 2012 c250 sedan loaner.

Interesting thing is that I definitely noticed right away that the sedan has much better throttle response and low end acceleration than my coupe. Also the turbo lag isn't as bad. Driving the loaner makes me feel like there is something wrong with my car.

I do have the BMS intake and tune installed on my coupe. Maybe the intake is killing me on lower RPMs or maybe there is something wrong with my car? I will try removing intake when I get my car back.

Anyone driven the coupe and sedan and experience the same?

I just picked up a 2013 coupe to replace the coupe I had that got flooded. Yes I noticed this within seconds of driving the car. Also I did notice the steering is a bit lighter than my old coupe than on this one. But I'm definitely feeling the power, I wonder how well it will react to the JB+ tune I'm getting in tomorrow

Also not to complain but I felt like the intake wasn't doing a whole lot of good for me when I had it on the car.

The 2012 loaner I have only has 10k miles on it so maybe it is a later build that has different ecu/turbo settings.

Do you mean that the intake was decreasing performance or just not having any gains at all?

Igor1080

I mean that the intake felt like it caused the sedan to lose throttle pressure after I installed it.

Kevin82

Yeah, short ram intakes will do that on the lower end rpms with gains on the higher end. I will take off when I get my car back to confirm.

Maybe I will skip the intake. Does it sound much better?

Kevin82

Yes it sounds much better because you get that hiss noise from the turbo. You can hear it with the windows up too.
