I currently have a clutch master clutch stage 3 and a lightweight flywheel, but I'm in need of a need clutch and I'll also replace the flywheel with a stock one. I know the gmpp clutch kit will work on my lnf and I'll need new lnf flywheel bolts, but will it hold full boost 20+ psi even in first gear? I'm on the stock turbo. Any input would be great or of any recommended clutch kits along with your review/prior experience with the kit.

GMPP clutch is more then capable. Shouldn't have and issue till you get in mid 350hp range in the worst case scenario.

350 to the crank or whp? Wouldn't it be depending on how much torque it's being put down?

It will hold just fine. It holds my 26psi (24psi for you sea level folks) and before when it spiked it held just fine then.

Also it's not going to slip in 1st gear, it would be more likely to slip in 4th (more load on the clutch face)

Well mine finally found its limit on my new engine. The old engine was 432/390 torque and it held just fine. New engine is most likely near 500/500, but it hasnt been dyno'd yet. As Ecaulk stated, mine started to slip in 4th on new engine. New clutch this spring!

Asking that clutch to hold 500 is a lot.

Yeah, I never really expected it to, but I didnt expect it to hold the old engine either, but it held up like a trooper. The stock piston ring lands however had enough after 4 years of 300-432 hp and 120k miles.

Impressive, looks like I'll settle for a gmpp clutch kit.

i dont recommend full boost in first gear, but yes this clutch is more than capable.

The owner before me put a zzp pcm I was looking for someone with hptuners in the NYC area to reduce it, but I've had the car like this since I got it 8 months ago.
