At first view, the flowmeters are 30% off (overestimating).
Then, the plan is to put the car in its original configuration and do FE tests at 90 km/h on a highway stretch and then to implement a new mod mod each time (the first one will be the changing the 5th gear ratio).
What was the price of your meters and do they have some flow restrictions? Are those meant for boat?

I tried to find cheap meter for my 6 liter turbo diesel scania, but what I found were over 1000€ per set.
