your stock clutch wont have any issues with just a chip and supporting mods. I pulled the original clutch out of mine at 120k and 50k of those were chipped and I basically drive it on either my race or extreme settings all the time unless im towing.
I would imagine my wifes 16k horse trailer and hauling hay were harder on it than the chip.
In the end its all in how you drive it.
