Just a quick question about traction control, does it slip the clutch to regain traction or cut fuel and spark or combo of both?

 

Traction control has nothing to do with the clutch at all. It will cut power by retarding timing and controlling the throttle body (maybe opening the wastegate to limit boost too, but this is speculation from my part)

 

when my traction control kicks in i loose boost altogether. Why would it slip the clutch, thats bad for for clutch.

 

Your clutch is a pretty mechanical piece of your car. There is nothing to control slipping of it except your foot.

 

Alright, i may be wrong but i thought like 03 1.8t gti's and stuff slipped the clutch when there was a sense of traction lose
