coach3062 Member 91 Member For: 18y 9m 18d Gender: Male Location: North west NSW Posted 17/03/08 06:16 AM Share Posted 17/03/08 06:16 AM My BA turbo ute that usually has 10psi and 290rwkws has dropped back to 7psi and less power.It has injectors, valve springs, monza cooler, hi-flow cat, ubp, plazaman piping kit, cai and normally goes well. Recently it lost power but still runs well (ie; smoothly,starts well, revs cleanly).So I checked all plumbing, new gapped iridium plugs, new air filter, lubed boost solenoid.No difference!I recently trailered my son-in-laws Calais (that felt good) a couple of hundred klms, but not too quickly. The problems started around that time.Is it likely the catalytic converter has gone to greener pastures? Any other likely causes? Link to comment Share on other sites More sharing options...
