Stock clutch slipping

[tneibling]

Since 2 days ago when I chipped up my truck, I have been noticing that under pretty hard acceleration in my 60hp+ tunes that my clutch will slip. It's ok for the most part if i keep it in stock and 40 setting. Supposedly before I bought my truck in January it had a new factory spec clutch put in but who knows if it really did considering some of the other things that I have found.

What aftermarket clutches have you guys had good luck with and recommend?
I don't plan on doing any major mods in the future (injectors or turbo) unless something needs replaced.

Valair and South Bend both have good products.
