Re: Air/fuel ratio?
Actually, I did go from #70 to #68 on the primary jets a week after the dyno pulls. I tested it on the Gtech, but really couldn't see a difference. Might have even dropped a couple hp. The plugs are a very light tan now which is about how I like them to look.
Seems like atmosphereic conditions make a lot of difference on the Gtech hp/torque runs though, so repeatability is always a question. They actually would have let me tune on the dyno for a price.
