. I accelerate hard as i come onto the motorway and it bucks slightly , which ended up me stopping the hard acceleration. I try again and it sounds as if the car isn't sparking correctly but it will allow me to accelerate on slow boost say 12psi instead of 15.I've had this numorus times now and it happens far more often when it's at 14.5psi and above
( 48 ratio on ebc ). If i lower the ebc to 46 ratio 14.2 psi it hardly ever happens.At one point last week though it was so bad i had to limp it home as it would not allow me to boost at all
, sounded as if a pipe was off or plug was loose.It has an FCD which is set to 17psi
, it has no error codes , the spark plugs are new , the leads are much less than 3000 miles old. The dizzy is in good condition as is the rotor arm. I've checked for boost leaks and i've found none!It's a rev 2 with a ct20b
, the odd thing is i cannot do anymore than 15psi the higher i raise the boost the more likely it is to happen and when it doesn't happen the car does not feel any faster. I'm also getting what can only be described as the odd miss feeling when the car is idling.
