Few questions
-have you measured that your DC is 100% of is this assumed?
-have you measured your fuel pressure is it identical to JAK's, the std fpr has a tolerance around +-0.1bar
-You are running your car with 1.5bar boost(2.5bar absolute) with the std. 2.5bar MAP-sensor, not good. The sensor is basically blind after 1.35bar (boost), ie. 2.35bar absolute pressure.
-injectors do flow different
-engines are never identical
Drew, there wont be much difference if you measure from before cat or at the tail pipe, basically the time delay is your only problem. BUT if the exhaust has leaks it will screw up the tail pipe measuremnt.
