You should get a wideband and see what your AFR's do on WOT......also just like everyone else said its probably your tune.

the afr's were good...and both tuners.....one in particular has done hundreds of evos in CT and New Jersey...the other is more for subies and mustangs and crazy cars but he does evos as well. both of these guys are the top ones in the north east from my research

Dude, you need some real data...else you cannot accurately find a correct solution. It could be anything really; phantom knock, bad knock sensor, timing issues, drivetrain harmonics, etc. Get some real data, then start figuring out what you need to do

Get the most recent ones and make sure they are full pulls from 2500 to redline.

I have ran 8es since the day I got my evo... I don't know about everyone else but my plugs have never lasted a year lol... Usually about every 6 months or so I change them.

Check your plugs and change if needed and see if that helps.

If you got tuned by junior I wouldn't listen to any of these people who are saying get a new tuner. I highly doubt its a timing issue if knock just suddenly onsets at 23 psi.

Buschur and others have reported those cams having phantom/false knock issues. That could be an issue. There are many other causes besides timing and AFR's.

Does anyone have anymore info on the Kelfords with respect to the phantom knock issue?
