i picked up a new gtp bout a month ago. hooked up the scan gauge to it. and its getting anywhere from 5 to 10 degrees of knock at wot and it started knocking last week. it has the power log on the front 3 inch dp into some cobbled together cat delete. zzp cold air intake 10.55mm wires and a zzp pcm. i changed the plugs in it yesterday to 103 autolites.... i cant figure out this car so any suggestions would be great. the afr at wot is 11.4. and it only registers knock sometimes but that is a bit high for my liking. plus with all the flowing mods on it why is it so high? fuel trims are zeroed out and between +- 5 at idle and beyond. fuel pressure at idle is 42. 52 without vacuum and i cant test it on the fly. ...help?
