I just installed an SLP lid tonight and went for a drive. Though I noticed a decent hp gain for a lid, the spark knock I once had is back. Anyone else have this problem after installing a lid? I checked all connections and fittings. Everything seems to be fine. Would the increased airflow lean out the mixture at all? The spark knock seems to be most noticable at WOT. Any ideas?

 

Well....driving the car to work this morning, I had no isues with spark knock. I guess it was just one of those freak things....I don't know.

 

The lid lets more air into the engine. More air equals leaner combustion, which can lead to knock, especially at WOT. Should be minimal, and the ECU will learn and compensate over time.

If you don't want to wait, get a few more mods and then get the car tuned.

 

I was hoping that would happen...seems like it already is. Thanks!

 

Thats good news... How is the knock still around of gone?
