Its show knock when it goes into boost on the scanmaster and the powerlogger. This a fresh build engine and trans and the builder isnt good at tuning. I have 60lb, turbo tweek, 5 disc vigilante,aluminum head(ported by champion) powerlogger and scanmaster with a wide band. The logs show plenty of fuel(10.0-10.8), timing 22/20, knock retard 0-15 deg, 18lb boost. It doest make any sense I have dual alky lines and I even put some c16 and still had at least 10 deg of knock. I replaced the plugs and went for a short drive and rolled into in for a couple seconds and the trottle completely went away and the car cut off. It runs and idle perfectly until it goes into boost. The only other thing I can think of is a bad knock sensor. I am very frustrated this has been a three year project any help will be greatly appreciated.
