Re: boost problems

1 thing to check is the BOV if you've got an after market one fitted,diaphram may have collapsed....also try connecting the Lambda,no point in having it disconnected...

as for ECU follow the Guide :- http://www.saxonfields.freeserve.co....htm#_Dyno_Runs and see what codes you get flash up

Re: boost problems

why is the lambda sensor disconnected?

Seems like it is in limp mode - possibly from large amounts of det from running lean.
