JB4 map 2. Cold air/ram air mod. GFB+ CAT BACK. MADNESS go pedal. Consistent logging at 25 to 28 psi at 6300 rpms......
More boost than you think

Youre not seeing 28psi at redline on stock turbo.
Giulia 2.0l redline is at 5800rpm. You have a tune that increases your redline to 6300rpm?

I did type wrong on rpm. Fat fingers. But here ya go
Thats 22psi at redline of 5800rpm
The rest are just spikes from jabbing and unjabbing the pedal
Do some logs in 4th gear or higher. Things happen too quickly in first gear and not enough load.

Blue line is boost. How is that 22?

Thats a little blip to 5100rpm. Not redline.
Log an actual gear from 2000rpm to redline youll see

I just installed new firmware to adress afr and ign. So I'll test tomorrow. Your 22psi argument is invalid
That log shows 22psi at redline. Just post the spreadsheet on Google drive and you can read the boost at 5800 but see below.
But if you want to see, again you need to grab 3rd or 4th or 5th gear and log from 2000rpm to redline. Log a single gear across the entire rev band
This is what your log should look like to show powerband...

Ok. One of us can't read the difference between INTAKE TEMP AND BOOST. LMFAO.

I mean honestly not looking to argue. Maybe I don't know how to interpret these logs. But even my boost gage spikes up over 30. Does it hold...no, of course not. My whole point has always been that with the build I AM getting boosts past the stated 22.
You're wrong.
Apparently not. Royal blue line is boost as both arrows point to.
Again, its all in your xml spreadsheet of the log. Post it and ill be happy to show you
It is spiking to your peak boost at a low rpm, but there is no way that it is holding that same boost level close to redline. Blue line is boost.
Thats not been your point. Your point was clear...
And its incorrect. No big deal.
We all know the turbo spikes at low rpm. It doesn't hold boost though. Its too small.

Got it. I'm new to turbos.
No biggie at all. Check your excel spreadsheet and compare to the graph results and it helps make sense of it.

Maybe at some point it would be nice to have a phone conversation? You could probably help me understand exactly how this all works
Sure.
Here on this log its one pull from 2k rpm to 6k rpm.
You see the green line is the rpm.
Now you can pick any point aling the green rpm line and follow it down on the vertical axis to one of your variables such as boost. And thats your boost at that rpm.
