So I just installed a fmic upper and lower ic piping and a synapse dv. Im getting a little studder/buck in second and third gear not all the time but still annoying is this from the dv its set up in push and a and b port

 

Tune? Are you getting the stutter at low RPM, part throttle?

I was a little confused by what you meant with "dv its set up in push and a and b port."

 

Yes I am just like that

 

And I have a cobb ap I get tunned april 1

 

i would talk to your tuner about the issue. make sure your dv is fully closed on idle could be you didn't put it on right. tuner should be able to fix that for you.

 

So if I put the stocker dv back on ill be fine and just wait til I go to get tuned

 

You're fine. The stutter at part throttle is normal, especially in higher gears. The change in intercooler piping may have exaggerated it a little, but it should be fine. Just make sure your synapse is set to full recirculation and not vta (atleast until you talk to your tuner).

 

Ok thanks guys
