Missing under load

[IBLOWN]

Sorry its not knocking i meant the timing is retarding. Why would that be if the the knock sensors arent detecting anything?

I havent logged a run since last night when the fuel was richer but the drivers side bank should have been seeing around 12.5:1 atleast.

not trying to be a smart ass but i had no end to ingintion leed issues, i found the extra heat of the turbo manifolds cooked alot of my leeds, topguns which resulted in them shorting to earth, was very odd would idle fine but once under load/rpm they would arch to the body.

Same problems i had on my VS turbo ^^ had my leads insulated with the orange tubing from pirtek but would still cook them after 3 or 4 months & cause all sorts of problems under load.

Hopefully it is just something easy to fix.

try 1mm gap on the plugs

factory v6 is 1mm and factory supercharged is 1.5
i do 1.3 aftermarket seems good for my car

factory is 1.5mm factory S/C is 1.3mm theres strange things a foot in the tune and fuel supply anyway. as its only swinging closed loop on one bank. its commanding 12:1 ratio when on boost and its definatly not getting that as o2 volts are well under 900mv .lean cruise both sensors cut right out to zero .few little spots of knock here and there but not much 4-8 degrees of retard thats being pulled easily by the ecu. so its safe.its knocking when it wants to .theres no regularity too it really. sometimes its retarding under no tps.

woops got that fully backwards hehehe
1.3 i run at as factory charged says, not 1mm hehe

Anything wrong with these? They have only done about an hours worth. I only richened the fuel up about 15mins before i took them out.

The one on the right looks like you might have some coolant leaking into the cylinder. If it only happens when hot it could explain it. As the engine heats up, the coolant pressurizes more and gets forced into the cylinder via a shagged intake manifold gasket.
