Can anyone tell me what sort of Boost Level I should be getting with a standard MY00ppp

I ask the question as I have finally fit a Boost Gauge and AFR and the Maximum Boost I could get in 3rd and 4th was about 14.5psi ?? Is this about right cos I believe I read somewhere that it should be more like 16.5psi ?

All views welcome

Boost mapped against Throttle position and Revs

Thanks for that Scott but can you kindly explain to me what I am looking at cos it looks very interesting.

This morning I managed to get the car on a dual carriageway and maximum boost was just over 15psi in 4th and 5th this was from 4K rpm upto about 5500K rpm. I was just interested in knowing whether I am getting the correct amount of boost with the PPP ?? I think if I am looking at this correct that at 6400rpm with full throttle boost would be 10.86psi ?? Sorry I am a bit naive about these things.

Target boost under 2800 rpm is 15.65psi, this drop slowly from there on to 10.86psi at 6400rpm at WOT (Wide Open Throttle).

In my experience most boost gauges over read by 1+ psi so it sounds like you doing O.K

on my standard ECU my boost gauge would read 14.5psi then drop to about 11.5psi as it reached the redline, although it is only mapped to 13.6psi to 3600rpm then dropping to 9.77psi at 6200rpm
