so ive fitted the gasket everyones talking about for the blt engine hesitation.i read tht you only need to drill it out to 12 mm at leist to stop the eml coming on.so i drilled it to 12mm.i knkw tht people drill it to 14mm.so this is my problem.. after fitting it drives so much better but every now any again i can still feel the hesitation.its no where near as bad as wht it was.is their some sort of software update required aswell after fitting? has anyone else came across this? if anyone could help much appreciated. thanks

no one?
