BD pro pushing plugs

[brodie]

12 pro with BD turbo he runs 7-10 pounds on straight av gas. It's pushing plugs once in awhile but not get any det. Lights or anything. Sled does hit rev limiter once in awhile is it possible over rev is pushing the plugs out and not pre det? He was told plugs only push from detonation but for his boost levels I think straight av is plenty of octane and with no det light just curious what u all think.

What elevation

 

[brodie]

7500ft-9500 ft

 

[TRS]

Plugs push from Det.

 

[brodie]

Ok other question being if they only push under det with no det lights or sled going into limp mode possible sensor issue or something then I'm assuming? It has yet to go into limp mode and has pushed plugs a few times

Det light only comes on if it happens for extended period or is severe. Make sure its got the ethanol plug installed and not the non ethanol plug or timing will be to far advanced

Very possible the plugs get loose from over reving under boost(not from detonation). In most cases people maxing out their gearing ratio(clutches and chain case(belt drive).

Can someone explain a little more about what this is?
