Twin, what year is your car? I know I'm beating a dead horse here, but I've never seen over 13 degrees advance. 12.5 is typical for me. e85, race gas mix, stock boost, high boost, water meth, 100% meth, cold days warm days, new plugs, old plugs. 12.5-13.
I'm a 16 sportwagen. I've seen as high as 18.5 degrees. It does drop under more boost. Especially with just 93, but George has said a few times that there will be a point in the top end that 1 psi is not worth 1 degree of timing loss. Too much heat being generated. I'm not sure at what point that is. Temperatures do make a difference, but with the meth, that shouldn't matter for you. I try to keep my settings so I'm at least 15-16 degrees above 6,000. What I found that helps is that I look for the spot where there is a dip of 2 degrees or more. If it's around say 4,000, I would drop the 4,000 by .5. If it was around 4,200, I would drop the 4,500 by .5. I know you said you don't get it on map 4 though. Not sure why
