I've searched and can't find a definate answer. I need to know if I can use a skunk2 manifold on the stock ecu. I have a 92 hatch with a 94 b18c1, vtec engages 5k. I'm looking for mid to top end power. Will I see gains putting it on without a different ecu? I have an aem intake, dc 4-1 header, n1 exhaust, b&m fpr. I just need to know if it will hurt me or help me putting it on without a different ecu. Sorry for a noob question.

 

yes it will make a difference but if you tune it for your setup you will see bigger numbers.
