Would you mind letting me know how you go with the wastegate dave? (ease of setting up the boost level and such)
also, i told you yours would be up and running before mine
you say 10psi and you don't get the issue 11psi and you do?
i would say the ECU is going into R&R. back the boost off to 10psi and your problem is gone.
candy33, i would get your brother to check that he has setup the injectors correctly on the ECU, he could be confusing a value of 95 on the fuel map as being 95% duty. what is the master value set to? (XXms)
on this image where is it showing 95?
