Also, just out of curiosity, does anyone else feel like this mod makes the 335 a little smoother at low rpms? I had the actuator unplugged for months and got used to it, then just this week I plugged it back in...I immediatly noticed the car would "shudder" much more when coming off the throttle at low rpms in 1st, 2nd, and even a bit in 3rd (I got the manual trans btw). In fact even my wife asked why I was having so much trouble being smooth  .
There wasn't a difference in the higher rpm range, but for around town driving the golf tee mod makes the off throttle response smoother for sure. I believe it has to do with backpressure, that is, having the flapper open reduces backpressure a bit and this improves the shuddering associated with the small turbos at low speed/rpms.
Now the question is, does the ecu adapt to having the flapper open all the time? Could this be why the shuddering got so magnified when I hooked it back up after so many months? Anyway, I unhooked it today after being annoyed by the head bobbing around town, and now the car is smoother again, go figure... |
you dont wanna do this. it will trow a code. not on the display of course.
hey it rhymes
