Well replaced the injector with 42's and put a waldo 255 pump . I'm wounding if just need to redo my V.E table and short fuel trims were +35% when a/f came back around 15 then when rev up the trim go back to +5% and the a/f goes to 19.1 and works way back to 35% on the short fuel trims. I'm thinking I should redo my v.e table for the bigger injector. I'm running co3 sem-closed looped and changed my fuel rate already. 58 psi with no vacuum and 50 psi with vacuum.
