I ended up with 12/-16 working the best for me. Remember, these settings are year specific and will vary some!!
I made around 10-12 runs over about 1 1/2 hours. Started fresh at 0/0 and went up from there. Once closer to the actual settings, I went one click at a time, setting the low end first, then the high side. Remember to reset the throttle (stab and release) after making your adjustments as explained in the manuel. I ended up with about 12 RWHP more than the settings that I drove into the shop with!!
BTW, Wes was very helpful!! Hope this helps.
