Boost problem Cosmo 13b
Hi
I can't get get my 13b Cosmo to boost enough. I got about 1,5psi from 2500-4000rpm and 7psi from 4000rpm.
I have changed all the hoses and checked all solenoids. The only thing that wasn't good was the charge relief valve, its stock open so I blinded it. I also opened up the cat. Anyone have some tips what too do next? What boost could I expect?
