Aaaand finally done tuning with Cary Jordan! We ended up at 22 PSI flat throughout the RPM band, and about 9.5 - 10 degrees of timing. I'm almost 100% sure there's more in it considering by average ignition on the JB4 is almost always at 0.0, but I'd rather have clean consistent power given that I also do track the car from time to time.
That being said, there is a dyno day coming up that I will be attending. Any guesses on horsepower numbers?
