Hi there, tuning a boosted 4.6 3v and cannot get it to add fuel at WOT/Open loop. I have two logs for your perusal, one showing 20lb/min MAF and 18% injector duty and 8ms pulsewidth (and lean misfiring), and another with the MAF scaled up to 28lb/min at the same RPM and load and still showing 18% injector duty and 8ms pulsewidth (and lean misfiring). Injectors are stock 03 cobra injectors which are 42lb/min at 43.5psi but running 60psi base pressure on this car to get more out of the relatively small injectors. Data is scaled accordingly in flow rate low and flow rate high. No fuel pressure issues, have twin walbros and a -8AN feed and pressure is rock solid during this issue.
