I did some repairs to my patrol (2001 gu zd30 di) it had low egts but insanely high boost (spiked to 28psi and then cut out to 0) replaced vac lines replaced fuel filter and replaced maf and fixed the intake hose to the turbo (it had a split in it). But now I'm getting max 8psi boost and then cuts out after cruising at 100 for about 5 seconds and just sits at 0 before I take my foot of then back on and we repeat the process and the egts head north of 600 degrees. Vacuum is good at about 95 kpa. Anybody got any ideas?
