Hey there, I have a 1998 Toyota Aristo VVTi
my mods are
Precision 62mm turbo
tial 44mm mvr wastegate
775cc fic injectors
aeromotive 340 pump
radium rail
mapecu3
aeromotive fpr
A340 with billet accumlators and transgo shift kit
Hallman and a Grimmspeed Manual Boost Controllers
-----------------------------------------------------------
I have a 10 psi wastegate spring put in, when I had it wastegate to compressor housing the boost would go from 9-10 psi in all gears.
I had hooked up my Hallman manual boost controller and between 5200-6000 rpm it drops from 14 psi to 10 and then it starts to go back up. I thought I might have had a faulty boost controller, So I pulled off my grimmspeed boost controller off my Probe Turbo and ran that and I have the same issue.
Now I just don't understand what it may be, Ive never ran into this kind of issue. Heres my Zeitronix logs I marked out where I did my pulls.
