since you have a boost controller you have eliminated on of those two methods perventing det. 675 turbos on NA pump is crazy, i can bearly believe it. Is it possible that the previous owner had fuel pump problems and it was replaced with TT pump on accident. Knock can be verrry quiet, i could only hear mine with the window down and my ear hanging out. sounded like a snank-crackle-pop or something sizzling on a skillet. My NA pump was getting noisy and dying before my swap, after the swap get got very loud, so i replaced it with a TT pump.
TT dynoed 340 rwhp 361rwtq before rebuild w/ SGP block/ GMS550BBs La-Z-Link.
