Oil viscosity 60 series 12.7
I have a 12.7 60 series Ddec Iv with a recent o/h. We installed a full tilt manifold hopefully to get passed the cracking problem with the stock ones that seam to break annually and a 171702 bw turbo. Calibration was done by a reputable tuner. Since then every oil change at 15000 fails drastically the vi index of 15w40 gets to 80- off the scale. Oxidation and nitration are high as well. Does anyone have any thoughts on this. Is the 1702 to big for this set up.

Put the factory programming back in and see if it still fails the oil analysis. Bad programming can do a lot of damage. Ensure it is not bad programming.
