Hi, I've been chasing false knock and I'm looking for ideas. I've checked all clearances, new HR mounts all around, new flex plate, tight converter bolts, new knock sensor, reset valves, ran 110 fuel through it at low boost, add and subtracted alky. I have a 210/215 Comp roller cam & lifters with Scorpion Rockers. I've got the valves all set individually at 3/4 of a turn past 0 preload. New Plugs set to .035". The knock retard happens at around 5600 rpm. More Powerlogger files available. Lots of fuel psi, and fat rich. Is that too high of rpm? I have one source that reads shift around 5,200? I have a few remaining ideas. Check crank end thrust? Could my timing be out?? chip default to 23* in 1/2 and 21* in 3/4. It happens in all gears over above rpm. Does Fast XFI use the stock knock sensor? Any suggestions would be appreciated.
Oh btw, 6.0 TurboTweak Chip.
Thanks
