After the build car ran great, after 1k miles, air fuel changed to 10 at wot. We adjusted the map pulled the timing by 2 deg and lower the boost to 20. Just to be safe. 3rd and 4th gear no knock at wot. When the car idles and if i you tap the gas pedal, knock shows 10 - 15 counts. Or if I drive 45mph and hit the gas to the floor on fift gear, Thers knock.... any ideas? I'm thinking to replace knock sensor , boost leak was done. Compression shows 180 across the board. Maf changed even ecu was replaced, just to check. No sound from the engine at idle and rev. Wide band replaced. I have 105k miles on the body and 4k on rebuilt. Mods are in my garage. Thanks, any input will be greatly appriciated
