Ah not at all. Just take a look at this video, and you'll get the idea bud.
Enjoy.

I did the same test as you, these are my results.
The Mode Test 3 100 Impulses 3.5 ms.
Press the petrol pump 49 psi.
Fuel injector is IWP 116 from a Punto 1.2
Hi pandablu,
Thanks a million for your test results.Would it be safe to say that the three
paragraphs represent
Pulse 1 in the first paragraph
Pulse 2 in the second paragraph, and
Pulse 3 in the paragraph. I hope I have this right.
I only used pulse 1 setting across the 4 injectors.
If I have this right, then comparing my results and your results in column/
paragraph 1 I'm losing around 5 psi, and your results show around 10 psi.
It would look like my injectors could be slightly blocked and need cleaning.
At this point I don't know the exact model of injectors installed, and to be
honest never really looked. Even though the car goes like a bullet further
investigation is needed, and if cleaning does bring my readings closer to
yours pandablu, then things can only get better.
100 mph..................UP the HILL!!!!!
Will you confirm for me pandablu when you get a chance, that I'm reading
correctly your test results. Making comparisons between same engines
really helps out. Thanks pandablu.

Hi,
I would not rely too much on pressure drop as an indication of injector flow rate. There are too many variables including trapped fuel volume and elasticity of flexible pipes. The fuel trim values will give you a better idea if flow is close to what the engine ECU expects the injectors to deliver. Only way to check for sure is to pull the injectors and squirt a known number of timed pulses into measuring cylinders and visually check the spray pattern (with fire precautions).

I did the second test. The device in Mode 2. In the first test it was in Mode 3.
