So my good friend got a dyno a few months ago and I was at his shop while he was tuning a lightning they had repaired after a blown motor. After we got done, he smiled and said lets throw it up there. It is always good to have friends that let you play with 20k plus shop toys. It is a dynocom he said it usually reads about 10% low from factory ratings. SAE corrected numbers were 398 hp 367 ftlbs on the first pull, and 392 hp 372 ftlbs on the second run. We were going to remove the restrictor plates and do a few more runs but I was out of time and had to be at work in an hour. If I bother to get the graphs, I will post them up.
