Tried stock and screenless on the Dyno. It Picked up slightly when I went to screenless. I then found out the REASON why. It was tuned overly rich before. (No screen) dropped what the Maf was SEEING for airflowflow, so the ecu responded by pulling fuel out....which leaned the mixture to the correct spot. In otherwords...I should have had it tuned right to begin with.

Does someone have a set with published tables to at least get you close, understanding things would need fine tuning on the car??
One reason I want to stick OEM is for the screen, with the intake I have it seems very sensitive, swapping from one filter to another one with an inverted cone one without caused big changes in airflow readings with a descreened MAF. I since put dual cones on it which may have helped calm the airflow.

The scoop is a RAISS intake, there is a plexi version called the SSRI, the y-pipe and filters I paid an arm and a leg for off ebay. Sort of wish I had just bought a pair of 90degree cut them and found someone to weld them.
The core support is one off an old cop car I put on after a deer hit, the car is not in that bad a shape.
The thing off the back of the pipe on the left is a spot for the IAT, but I have that mounted between the MAF and TB.

I descreened mine, cutout the divider plates, and even trimmed the uneeded plastic from the sensor itself. That was 8yrs ago, car has always ran just fine. Makes damn good power with unported factory castings too.

You can do a lot to a MAF if you tune it afterwards, BUT screwing with it will make tuning more challenging. Now those who have done it and recommend it d you any proof that screwing with it helped make the power you have?? If not all you accomplished was making tuning harder.

I have descreened my stock MAF and ported stock ends. I did this mod on all my LS1 cars since year 2000 when installuniversity.com had this first mod. NO PROBLEMS. I was very careful when I ported the ends just like they said. I had car tuned and dynoed after all this and my afr was 12.8-13.1 up to 6000 rpms. I think it is a great free mod with more air flow. IMO
I would like to ad that I did have a leaner afr at first dyno, but that was because I had a bad front O2 sensor. Got it fixed and car running great. Had car on tech 2 GM Dealer. All peramitors were normal. It is a great free mod IMO.

i went all of the way with the MAF.
i descreened and ported and polished (3 stages of rubbing compound after 1000 grit) the MAF when i was doing induction work. the car has ran stronger and better.
no lean issues. no misfiring. no codes. running like a champ.
