As the title says the MAF threw a code whilst on the motorway and at the same time the turbo fails to boost over 60-75 mph. Yet from what I’ve heard the MAF will always show the code when it’s on its way out. Just want some opinions and ideas of this. Like my previous post it overboosts normally, over injects fuel when demanded yet not when the turbo refused to boost (not got that sorted out yet). MAF reading at idle is 8-12 g/s and 124.9 at full throttle in 3rd, boost pressure is 23 PSI. Not checked for any leaking boost pipes but not a problem at air filter to MAF.

I would like to see what people think about this.
Thanks
