Clutch won't disengage

[Kspen90]

I have a 2002 lb7 with the zf6 manual. I have +80hp injectors, and a small superchips tune, and a cold air intake with the stock clutch and trans. When I turn the programmer up to level 2 and get on it a little the clutch pedal gets so hard to push in that it feels like the pedal will break if I force it to disengage the clutch so I push the throttle a little and float it into neutral. Any ideas why it's doing this?

You have the systems of the infamous Hard Peddle Syndrome. It is caused from the clutch slipping and heating up. It may be time for a new clutch. Sorry.

I like mine. I have the Valair Ceramic/Kevlar single. I wish I got the DD thow. I am at the power limit of the single, but it is still holding.

Yep your clutch is slipping and boiling the fluid in the system. A quick fix is to turn the power back down and try to get as much of the burnt fluid out as you can and replace with new it will help a little. But your going to need or want a DD.
