Cosworth seems to misfire when boost kicks in , could this be down to my plug gap ??

I've ordered a new set today the cars running stage 3 any know or can tell me the correct plug gap running this kinda spec

Thanks anthony

 

bump....

 

gap is usually 25 thou for stage 3

 

25???? I was thinking 0.6 ??

 

25 thou is 0.635 mm so damn close.

 

Thanks lads

 

Any joy mate
