Nope, still has not been properly tuned. Eric & I leaned it out a little, but it was the 2" headers & 3" exhaust that picked up 40+ HP & 80+ ft-lbs.
The day it made 398 hp, there was a guy in from Cleveland to tune it, but I had troubles with my ignition & it would not start for an hour (plus I had to wait for two other cars). He couldn’t wait around, so when I finally got it running around 5-6pm, we just decided to put it on the dyno anyway & get some base figures.
