    So I have an issue with the 3 where after a pull, or even just a decent amount of boost the feel of the clutch changes. The engagement point will be on the floor, pump the pedal 3 or 4 times and it will go back to normal.

    I am going to bleed the clutch line, but i figured if there was air in there this would be present always, not just after seeing boost. Has anyone ran into something similar before?

    I totally forgot about that, Andrew, lol. She'd done it for as long as I owned the car; wouldn't do it consistently after every single hard pull but only ever did it after one, if the way I worded that makes sense. I researched it multiple times at various points and found other people with the same experience, but noone had ever really figured out the cause. Definitely give it a good bleed to make sure but don't be surprised if that doesn't have too much of an effect.

    I think someone from FL posted about this a few years ago. IIRC it was an issue with the slave, but he ended up replacing his whole clutch.

    I'm having a similar issue with the mustang, but that's an issue with improper shimming of the slave since its inside the bellhousing. Whole other monster of a slave, but it happens when the car is parked hot for a while, or after driving for a few miles on the highway. On that car the most effective solution is to shim the slave properly.

    I would start with a good power bleed, and check the extension length of your slave.
