Mesh filter removed and Edelbrock pro-flo urethane filter media ziptied on speed star velocity staks.

Did you notice any change in performance? I would like to do that to mine, too much dirt on the roads around here.

As far as puttin on the Speed* velocity staks, or wrappin the staks with Edelbrock Pro Flo filter media from AdvanceAuto or Autozone? The performance really picked up after the custom map. It just ran leaner with the staks and filters with the stock map. It does have the PCIII usb. You can't go wrong with a VBAK and a custom map.

I'm sorry what is custom map?
