[QUOTE="6.0 Tech, post: 1354259, member: 23001"] Sorry, as stated koeo is key on engine off. 23 psi seems low. When driving monitor vgt duty cycle in percent. If at any time it sits at 14.99% or 84.99% they are sticking. And when checking pressure at koeo, also check map and baro. All pressures should be damn close to each other. Ford says within 1.5 psi, but real world testing is usually between equal to .5 or .6 psi of eachother. [/QUOTE]
