I haven't changed where my vacuum pressure is being read from...the DEFI gauge is connected at the same place.
What I was trying to determine was whether the increase in vacuum pressure was something to get concerned over, or if it was a positive effect influenced by the intercooler. I suspect with an upgraded intercooler with it's increased mass/air flow, etc. this has caused my previous value of 20 to change to 22-24.
I can't remember where, but somewhere on this forum, it was suggested that if vacuum pressure was to increase from 20 then there could be a potential problem....hence the question to see if the change was expected/normal after the addition of a intercooler and HPFP.
By the sounds of it...looks like my car is behaving normally if the consensus is that the readings are in the region of 22-24.
