    Changed maf and plugs today and car is pulling much better low down and off boost so win there
    I can tell there is a boost leak somewhere but it seems like at high rpm its hitting some sort of protection, then after about a second or 2 of then it goes fine again then does it again just before hitting redline. Here is a couple of logs anyway, cant do any better ones as ive only got vcds lite.

    and what i think is the n75 duty cycle is 100 all the way through the revs, accidently cut it out of the log

    You're pretty much maxing out your injectors.
    20ms at 6000 rpm is 100% duty cycle.
    Specs of the car?

    yeah more logs would be ideal, i might go on a hunt for a garage with a smoke machine tomorrow and see what that finds, someone on vwvortex has suggested changing the fuel filter so i will do that tomorrow aswell.
