just put on new clean 460's and a new hks bov and im getting a studder going in to boost but after 4000rpms its smooth and going up to 3000rpms thats when it starts i thought I fixed this by messing with the openloop settings, and recalibrating the injectors can someone help?

 

post up your tune

 

Also, please post a data log of it happening. If you had tried to fix it with changing the open loop settings, that's a sign your VE table is off.

 

I also am getting this. Very bloody annoying! I moved my map location and it fixed it a little bit!

Will be keeping an eye on this thread!

 

i got fed up with it and tried blowing the motor, so the car won and i sold the mspnp.
