I actually kinda like the slow throttle response....

[SoCalGen]

Coming from a GMC Yukon the Genesis is nicer to drive from a complete stop. In the Yukon which had a V8 and gearing for a truck if you had a heavy foot you'd almost give yourself whiplash from a stop due to the 3.73 rear diff and low end torque. The Genesis has this nice gradual but authoritative forward acceleration which I think adds to the luxuriousness of the car. Of course if you really want to go fast you can mash your foot down and it will take off like a rocket.

I know what you're saying but sometimes I just want to drive more aggressively. With the Sprint-Booster I can have the aggressive driving mode with the options of toning things down when I want a more casual, luxurious drive. It's really a great feature to have available. It is also beneficial to have quick throttle response when I want to pull out into traffic and need to get up and go quickly.

The problem is, when it takes almost two seconds to start to do anything, that is not an ideal situation. Sometimes downright dangerous.

This just happened to me on the freeway right after I wrote this post. First I thought there was something wrong with the car but then it acted like normal again.

Turns out there's an easy fix...

Excellent, please do share....

I think that daviderle and amartz are referring to the thread below. I have done this VERY easy 5 minute modification on my 2014 RSpec and have noticed a significant reduction in the transmission response time when downshifting. daviderle did a fantastic job in finding this modification and quantifying the results as outlined in the thread and thanks much to amartz as well for additional information provided on this.

Interesting. I might have to give that a shot.

I did this mod. Big difference .. very happy.

Read my post in the above thread.

I've always thought the R-Spec's throttle is too jumpy. After not driving my parent's Gennie for awhile, I break the tires loose so ridiculously easy. I get acclimated to it fairly quickly, but my 550i and my brother's Navigator have much easier pedals to modulate.

After a few months I've changed my mind and now I hate the slow throttle response. Going to do the gorilla tape/flapper door mod this weekend and maybe drop in a K&N filter.

 

[OneFunGenesis]

Haha thank you for the update. It's interesting how tastes change!

Welcome to the mad house

LOL Thanks guys!

So is Gorilla Tape the accepted standard now? It seems people were using those little felt adhesive pads before with some success. I'm sure the Gorilla Tape holds better.

I think most have setteled on switching the magnet around if you like a bit of work:

But the Gorilla Tape will be almost as good, just make sure the magnet forces are sufficiently weakened.

And please do not forget to update the poll / thread after couple of days of trying it...

Will do!

My update after testing the secondary inlet damper mod.

I'm thinking it might be helpful if those commenting on this intake damper mod could provide the engine type and year as well.

I have a 2012 Sedan 5.0. I used two felt pads to reduce the magnetic effect on the intake damper.

I found no difference in off the line performance and, if anything, it seemed to slow down the throttle response when going WOT from 20 - 30 mph. It seemed to slightly delay the transmission downshift.

In looking at my intake I see four intake air routes. The primary box has an intake filter which I assume is used at idle and other times of low power production.
There are 3 separate intakes to the main intake duct which are all controlled by the air flapper valve. I am thinking that that Hyundai provided this mechanism to protect the transmission, but there also may be other reasons which I don't comprehend. Perhaps gas mileage.

Still thinking about this and may try it again, but I have never experienced any degree of throttle response delay with my White Genny. So far, only 4,000 trouble free miles.

If you've never experienced the delay in the first place then that would likely be why you didn't see an improvement with the "fix". It's possible your car has slightly weaker magnets to open the flap sooner or maybe the 5.0 draws more vacuum? I totally notice it in my 3.8 and although it's not a HUGE problem it is annoying when trying to aggressively pull out into traffic as I often have to to do living in Los Angeles.
