I tried to get a video of it earlier, but with the exhaust and road noise I couldn't hear it on the video.. But as far as the knock goes... I have not asked them, But to me it doesn't come from the engine, it comes more from right by the x-pipe, and also the front end of driveshaft where the sheet metal is. Does the sound come directly from the engine or would I hear it further back if it was a knock? And I'm not sure if this matters or not, but I tried just doing a rev while in park, and it makes no sound in higher RPM.
If it only does it under load, it very well could be knock. Datalog your car and send it to Lund so he can look at it Sent from AutoGuide.com Free App
