MAF modification

[vt_II_senator_sig]

Hi all,
I had heard the the Maf that are on the ls1 are from the American market, and the reason for the honeycomb flutes inside are due to the fact that their maf is located next to their throttle body, so the flutes make sure that the air is flowing straight through the throttle body and not at an angle to it... Since our maf is midway between the throttle body and the airbox, i have heard that if you carefully remove the honeycomb without damaging the sensor, you increase the airflow which in turn can create a power gain.
It sounds like a cheap and easy way to make a power gain... if its true and not complete rubbish.
I was wondering if anyone knows the truth?

why mess around with a ultra-restrictive maf sensor? stuff all gains to be made pulling the honeycomb bit out. mafless tune is the first thing to do for real gains.

why dont u get a mafless tune and remove the maf all together? no restriction at all?

If you wanted to keep your MAF for reasons apart from extra tuning and power, or cause ppl tell u to remove it. Yes, removing the MAF mesh, and maybe a slight honing, can gain a few KW's

Do not pull out the screen as it will make the maf inaccurate. The screen is there to promote laminar flow over the wire element.
You would be better off putting it in the bin after a tuner has done his work.:whistling

that is false
if you want to retain the maf
get a mafless tune and bore the **** out if it and pull the guts out
so it looks factory but it isnt really doing anything

****ing with the MAF will cause severe problems , especially with an A4 car

get it tuned and throw it in the bin
