What did the before and after flow rates look like?
Sorry Bobby - missed your reply
There wasn't that much improvement, the report contained all sorts of tests results - the below figures are injector number, static flow before (I assume in ml), static flow after and the percentage difference:
1 119 119 0.0%
2 118 119 0.85%
3 118 120 1.69%
4 117 118 0.85%
It was more a case of knowing they are working...but would have liked them all to be flowing the same as No.3!
