Darius - your pressure should RISE when you gas from idle wth vacuum attached. If it doesn't, something is wrong.

initially it falls a bit....then it rises the more you gas it , but off idle at first it falls for a split second or maybe even a full one......hmmm filter is supposed to be under 5k .....new dampner..adjustable fpr..some have said the fixed 3 bar Bosch is better

Check the vacuum for this. The FPR vacuum is VERY VERY important especally on a modifed car.
