I am wondering if raising the engine compression to 9-1 or 9-5 to 1 would build more power at current boost levels. Also it should help raise engine vac as long as u don't put a cam in with more overlap I think. Been wrong before so what do u think?:confused:
 
raising the compression would increase power. make sure to run premium fuel. 93 octane, or 91 in some places of the u.s. your knock sensor will take care of pulling timing.
