Car doesnt buck/hesitate when leting off the throttle at wot it only does it in boost and part throttle.
Car has forge 007s with yellow springs and 1 shim that i just re greased last month.
Any idea of what it could be? Its as soon as i let off the throttle it will buck slightly.
not sure ive had this happen before, maybe something similar. check all the basics before getting to crazy with diag. it would appear related to the dv's since it does it when you let off the throttle. could be a slight crack in one or both dv diaphragm. that's where I would start. throttle body boot is a good place to start. cover all your bases on boost leaks. small cracks or tears can be really difficult to see, but they open up when boost is present. weird you don't have any codes.... also leads to believe its something related to dv's off throttle. just my .02
