Al at garage advance said this was knock...do you think its true? Right where it levels off,then drops down? I think this is just the boost creeping down, because when I drive it daily, and race it, I don't feel it slowing down at all. This dyno was with a homemade ball and spring boost controller. Thanks for opinions/advice.

Yeah, he said it was sensing knock and retarding timing.

How can you sense knock? I know you can hear rod knock. It sounds like he means detonation. Rod knock will be something you can hear.

Well if your EGT's were shooting up up really fast at a the start of a certin RPM and the Air Fule is still good then. Yeah it's knock. The Knock sensor could be pulling timming but you prob would hear it pinging.

knock is exactely what everyone else is saying, it has nothing to do with rod knock, just like yellow4g said egt's climb but the car feels like it isnt going anywhere.

My car was not doing anything out of the ordinary, as in noises, bucking, slow rev's, anything. It was revving up fine. I wish I could dyno again, so I could see if, on low low boost, my car will keep climbing, because I am pretty sure it was just the boost going down.

Thanks for the help, and Mark I await your presence. I decided that...since exhaust is holding me back...when I go to the track tomorrow, I'll just leave the exhaust off! Woohoo!

Justin!

1. The spark plugs are not bad, if a spark plug wasn't firing, the car would feel stock, or much slower. I ran a [email protected] tonight, so I don't think the car is exactly running slow hehe.

I think it is a big tuning issue. I think about an hour of messing with it should help out a lot!
