I changed the MAF because mine was reading a little low
i recently put in a walbro 340 and chip and hotwired it
why am i still getting knock
i get it with dump both closed and open
i get it when i build boost 15 psi and above i think
if i plant my foot off idle i get the typical stumble (009s) then the boost builds and POP i get a lot of knock (11 degrees approx sometimes more or less) and a popping noise
if i ease into the car and build boost slowly its a little better but not much i still get knock just no popping
any ideas or things to look for????
HEEELLLPPPP
