TB/Plenum may only add a couple hp..... Im on the stock one for now. I heard that the TB/Plenum combos can lean out your a/f ratio up to 30%, so I wanna stay nice and rich for the n20. Maybe when I get a tuner, ill throw in the combo, and add fuel...

A guy on another board had his car dynoed before and after the TB/Plenum combo with a/f readings. He said his leaned out around 30% untuned. There are some graphs of his runs somewhere. Then after he tuned it, the combo actually made some power.
