Over the past few days I've noticed that my throttle is hyper jumpy. especially in first or second I can barely touch the throttle and it will jump quickly and then back down. Another instance is that I'll be on the throttle just a little bit and it won't accelerate consistently. It will accelerate smoothly and then all of a sudden the boost will jump and it will take off, then the boost will drop off and it will go back to normal. So it's really jumpy and amidst all this I am getting turbo flutter. Sometimes it's just straight flutter and other times it will flutter for a second and then I'll hear the ppppshshhshshshsh of the BPV.

I have the K&N SRI, GMS1 and the forge BPV. Does anyone know what this could be and how to fix it? Help is appreciated. Thanks

 

Are you throwing any codes? We are probably going to need a little more info.

I would try and lube the forge BPV if you haven't tried that yet. Then, I would say check all your Vacuum lines for leaks. Should be a good start.

 

Probably an air leak. Check o-rings on your MAP sensors. They should be blue, not green. Also clean them off with MAF cleaner while you're at it. Go from there.

 

This occurred after I recently cleaned the upper MAP sensor. The only code I've thrown recently was a P106, hence why I cleaned the upper sensor. I've never done a boost leak test and am wondering if a boost leak could cause that.
