well with 15 psi of boost wouldnt we be making more than with 10 psi of boost? so if thats true then headstuds can help with performance cas they allow you to run higher boost and that allows you to make more horse power correct?

 

its not them solely that allow the higher boost, as said previously, u can run higher, but not for as long...all they get upgraded for is reliability...something else to think about when building and tuning engines...
