Ive read the articles aswell, They make for a good read...!
Im going to try my standard fuel reg today and see what diff that makes, its not so much "missfiring" on boost, its more turbo stall as it boosts up the boost gauge flicks back to zero and then to the boost level... Only over 0.5bar, but i can hold more than that. Just every now and then it turbo stalls!
