As per email , the boost was measured from
The cold side intercooler to tb pipe , this was drilled and tapped to suit tho as my water meh controller needed a boost input

Just out of curiosity why do you want to know the boost levels so much ?

Also doubt they will run the afr gauge in the exhaust , diesels have a much wider range I'm sure so 9/10 there wide bands won't be wide enough lol
