505 rwhp on an LLY with #2 fuel only on a stock turbo? (Are there any inerds changed or modified from factory?) That has to be the number to beat! Very impressive indeed! If you had dyno`ed in 4th gear, the hp would down slightly, but torque would be even higherI dyno'd Kennedy Diesels tunes on a dynojet this morning, the 190 tune laid down 505rwhp and 1002rwtq in 5th gear. I'll follow up with more info when I finish up for the day.
