No detonation under any conditions I could induce including WOT, highway cruise, and pulling inclines at low RPM. I had to back initial down to 11* due to hard hot-turnover and ended with 33 at 2800 RPM. also adjusted the idle AFR using a vacuum gauge. I am very happy with the results of the total tune!
