rwhp increase after break-in?... When I had my dyno-tune on the 383, I had ~1000 miles on it. I've got about 10,000 miles on it now and an ASP crank Pulley. I'll be at futral getting some more tuning done on it. What should it be making now? Maybe 390-395rwhp? All other info is in the sig.
I'm sure you'll see a little improvement, but I wouldn't expect a ton. The rings should have been pretty well seated with 1000 miles on the clock......I'd guess 5-10rwhp, all other conditions equal.
