Has anybody actualy ported their maf and if you have does it affect anything at all or is it just another thing you can do to decrease air resistants.

Not worth it you won't have any gains at all.

x2. The only way to see gains is to port/polish the LIM and UIM, larger throttle body and then add an LS1 or LS6 MAF and retune the PCM.

:horse::banghead:hammer: A 5 second search produced this. unscreening maf (http://www.grandamgt.com/forum/showthread.php?t=78271&highlight=maf+screen)

There are many other threads on here that mention this too. Basically taking out the screen and/or trying to port the MAF DOES NOT WORK!!!!.

It is a delicate electronic sensor and is precisely calibrated to measure air flow through an opening of a specific size and characteristic. ANY change to the opening will make the sensor reading inaccurate. :nono:
