best off finding people with all the different set ups and just fit them all to one car at a time and see the difference. be good to do stage 1 car and a stage 2 car as most people only go to stage 1 and then people who want bigger bills head to stage 2 and over i find.
 
Also have to look at fuel trims to get the full picture

Bit off topic maybe but; Wouldn't it take too long as surely you'd be interested in seeing the long term fuel trim after a clear out of the memory?
Or is the logic that if the sensors report a "stronger" lean state (higher trim response from ECU), it means more O2 being sucked in?

Yeah long term result would be what you are after, can read the info from the cars the intakes come off, will give a general idea at least
 
And if there could be one for diesel.... :)
Prove that no intake makes a noticeable difference. Or something.


...I just want to be part of the gang :(
 
This would be very interesting to see the actual differences in intakes.
I have the Evoms induction sat waiting to fit to my car.
 
Jumping in here got a ibiza 1.8T cupra stage 2 with just a cone on it looking at a ITG.

wouldnt you need to run the car with the filters for a period of time to allow the fuel trims to adapt to the different MAF readings and filter to get the best results ?
