StainedBedSheet Posted October 16, 2018 Share Posted October 16, 2018 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. ------------------------- http://s000.tinyupload.com/?file_id=83221953599613226723 Quote Link to comment Share on other sites More sharing options...
