How so? Is it when you shift gears? Is it just when you are climbing RPM, it starts to flutter? Does it bog? Can you "feel" the motor hesitate?

is it the blow off valve?

Sounds like one of your vacuum lines isn't on properly. Check/remove all the connections to ensure there is vacuum and that the lines are on the rgt nipples.

yea when it gets to higher rpms starting from around 4K as it climbs... i checked all my vaccum and seems to be ok

Did you try loosening the bov screw at all?? I bet the shop forgot toadjust the bov

i was thinking back spin myself but that is impossible if the fluttering is occuring during RPM climb unless ofcourse the compressor or turbine is bad.

how do you adjust the hks bov???
could it be cuz its not tuned??
and when my cars idling i hear a lot of air coming out of my bov is that normal?

your bov is way loose. I dont' think you can adjust the hks bov? Does it idle ok?

I don't think it's the blow off valve. If it is doing it while accelerating, it's the engine. Is it just a noise, or a feeling? You need to answer my original question so we can help.
