Going very lean up top Lots of knock tephra v7
Ok I just switched back to a stock ix turbo from a 6262 and I switched to tephra v7 with speed density. I keep getting lots of knock during spool up 15-25 counts that i can not get to go away, I have adjusted fuel and timing. It is also going very lean around 4500 rpms it leans out to 15.0 and I have tried adjusting my rpm ve tables and my map sensor ve calibration table and nothing seems to help. Any ideas on where to start?

Sorry to thread jack but I have a similar issue. All is fine till about 4k when it goes very lean, im running tephra v7 with SD 2.0 if that makes any difference. Anyone have any ideas as to what could cause this problem? Assuming all mechanical components have already been ruled out.

im thinking its phantom knock. we have this problem alot on 10's also that when the timing below 100 load on the high octane map is different than the timing on the low octane map, and it causes some type of phantom knock. so basically we just copy everything 100 and below on the high octane map, and paste it on the low octane map, and it solves the problem
