Well I dont want to get excited to soon but the car was fine this morning on my 10 miles drive to work. I'll see if its ok on the way home but im pretty confident by now I would be in limp mode!
I will be getting a new/used N75 as I dont want to run with just the MBC but it appears this may be the fault.
Thanks again for all the help and pointers!

Think thats what I'm going to do Bill, Now I know the fault was the N75. I'll use both when I have a new N75 and see how I get on.

Check my readers ride thread its on page 10. I use mine to bleed off any boost over 1.7bar
My money's still on the map, LOL

Whilst reading about I can see that many prefer to run it with the N75 as opposed to taking that out completely so I for one will be doing it like this. Hope you get the car fixed mate!
Cheers El, Im 99% sure it was the N75 as the car has been fine since removing it and just running with the MBC so I'm going to get another N75 so as not just to run with the MBC just incase it did fail!

Me7 can deviate over time and cause flare up if there are issues , boost leak ect . These K04 hybrids are very temperamental to tune and you really have to tune them in a totally different way you tune a std car
Remember , ME7 doesn't request boost , it request torque , aka airmass . turbo control maps are only really a character on how the turbo responds.
Try this , put your n75 back on . With vcds , go to engine 01 and in adaptions , put in 000
and press save , in basic settings , go to 98 and do a throttle calibration.
You might find the car will drive good again , for a while anyway

throttle calibration on this ecu will be basic setting ch60?
I have been reading up and talking to my tuner who says there are boost maps which take into accout atmospheric pressure and altitude so the ecu works from load map which with corrections work out to be exact boost request.
I spent a few hour at my tuners yesterday watching them custom map a ko4 hyybrid via the n75 system. It seems there is lot of work involved.
