Good info here. Has anyone found the max boost pressure the LC9 valve springs can hold? I may run 9psi when I get the kit. Cant wait to make this truck a little quicker.

Bret at XP told me not to go over 10lbs and that even at 9lbs the stock springs will be to weak after about 20,000 miles after boosting it.

honestly the LC9 springs are weak for NA setup, when you can compress them in your hand they are too weak but they were never intended for performance but for gas mileage

Sounds like another grand towards cam, ls7 lifters, valley cover, etc after the turbo install.
