im about to buy a 2002 lightning that has 50000 miles on it. has full bassani exhaust, different cam(stage2 comp cam), and intake and jlp chip on it. he says hes running 14 pounds of boost is that to much for stock internals?

 

Nope.

hes not making 14# unless he has it pullied. you lost boost with cams because you flow more air.
