Hi guys, just wanted a little advice please.
Had my bigger turbo mapped and top end power and boost control seems good but I now get an under boost fault when cruising at 70mph.
I have done a quick data log.
Column H is rpm, I is requested boost and J is actual.
This was at a steady 70mph cruise and you can see it's not under full load because the revs are staying between 2184 and 2247, I can't see why it's requesting 1.3-1.4 bar of boost with so little load?.
Limp mode was when the requested went to 1550 mbar.
