Becuase of a few things:
1. If you have a stock headgasket say goodbye to that. You want more boost than 9_PSI? Buy a BHG.
2. You will hit fuel cut past this. (9 _PSI is a rough number)
thank you very much
what about if u already got a MHG ( i think thats what u meant too)
and i know weathere is a factor too
what about if its about 30' outside?

no you wont hit fuel cut after 9 psi. ppl boost up to 15psi on the ct26 before fc, however the ct-26 is said to lose effeciency after 13psi. also if you've already retorqued the head turnin up the boost a lil will be fine. and ive heard the stock internals are good up to i think its 500hp but im sure if you get up that high you may have already changed them
