Hi all! - 2007 Fiat Bravo 1.9 Multi-jet 150 Sport, ~114k miles

My Bravo is having a recurrent turbo pressure code come up. When accelerating up an incline (not even one that should hinder a 150 BHP turbo diesel) it seems to struggle in the higher end of the revs. Around 3-4 thousand, it’ll “cut out”, cutting all power and triggering the engine management light. Each time this occurs, it scans up with the same turbo pressure code “P0237”. It has no DPF and the turbo veins have been cleaned. Any ideas or similar experiences? Mechanic fiancé is stumped. Wanting to get it remapped, but can’t as I fear it’ll cause it to trigger even more.
Thanks in advance for any replies!

Have the multiecuscan and measure live data. Boost pressure, pressure sensor voltage. Hope it helps figure out what goes on.
