Entirely depends on age\condition of the clutch, engine\state of tune and driving style. Some say anything past stage one will kill it, others have used OEM with stage 2+ for a time with no probs. It's impossible to say it'll die after X number of miles or Y power\torque figures.
From what I've researched basically if in good nick it's life will be reduced but should hold up to anything below stage 2+, if already borderline then good luck to you.
For reference my FR TFSI was running stage 1 w/ 251/
290 with a fresh OEM clutch for 20k miles, have since covered another 5k with stage 2 274/327, no issues. I believe the car had done 5 years & 40k previous to that lot with the original clutch on the stage 1, along with the mileage on standard tune from new. Now on 96k so they last well. I'm tempted to go 2+ and take a chance on the clutch as it's so fresh.
