ported SLP's.Last week installed air/fuel gauge and been driving it w/SLP runners.Switched to the stock runners and while taking it out on the test run noticed that it ran alot leaner w/the stock runners.Didn't change anything but the runners btw.Noticed last yr that it ran better times w/stock runners than the SLP's.
