    Nope. All OEM allegedly. If i let of as gently as possible it doesnt happen. Just one hard deceleration if im not careful. Not normal?

    Nope. My car doesn't sound like it has a BOV. Everything looks stock.

    Let off - I've had my foot slip off the clutch, causing it to be released quickly, and it bucked a little bit.

    Not like that.

    This is when im accelerating say about 5500 and let off the gas to go to a cruizing pace. stay in gear but cease the acceleration. foots nowhere near the clutch. However, this DOESNT occur when i depress the clutch as i let off the gas.

    It almost feels like i jammed on the brakes for a split second. Just enough to feel it.
