ok, ive just fitted a K+N gen II and the boost keeps backing off, then back on again,

spoke to nathr, (best mate and fellow FRS owner) and he said hes had this problem but just resets bluefin and its fine,

i disconected the battery for a while, took it down the road and thought spot on, not a problem, drove it the next day and the same broblem just not as bad.

any sugestions,

the MAF is clean and there are no leaks from the filter,
