Did you yet?
& &.........?
If you are experiencing a problem or believe fuel PSI or volume related, however, it isn't shown in blocks, don't you think, mechanical or actual volume tests should never be negated?
Did you know you can have PSI all day long in a controller block or even a mechanical PSI gauge and no volume?
Did you know some tuners or hacks tweak the stack to delete trouble codes or even actual specified tables to reflect a better outcome or actual tables & also possibly modified by tweaking the report table calculation too?
Point "is", sort of trust but verify in this day in age, the data "is" what it "is" & as it reports what it "is" in comparison but what does "is" really mean?
Don't just pay attention to block PSI either because did you know that duty cycle plays a significant roll in achieving that specified target?
For example if the cycle was pinned at 100% this would imply lots of work is being done by controller switching to maintain that target, the more you know right?
