update*** got truck up and operating this evening. I am really surprised on this setup, should have went to non vgt a long time ago. the 64.5 hardly has any lag, or matt at ******** nailed the tune. this setup compared to my 68mm vgt turbo is the same lag wise but power? the 64.5 bw blows away the 68mm vgt (don't have numbers but truck pulls way way harder with the non vgt).
I am also pleased to see very low egts, I couldn't for the life of me get the egts any higher than 1,260 give or take degrees(******** srlxx tune reduced fuel), and cruising is between 490-680 degrees depending on incline. so far I am very pleased with this setup, the sound is killer as well, unique fore sure. Only thing left to do is re position the dp so it stops hitting the frame.
with a regulated return, new hfcm pump, 6.4 hfcm pump, and sump, I hold 60 psi at all times with the holders 205/75 injectors(just some additional info).
