IMO that looks fine but depending on how it interpolates from cruise to WOT it may be a bit "spicy" and ping. I tend to ramp timing out from cruise and my WOT timing is usually around 85kpa and I just copy/paste up to 100kpa. If you can build a table on the laptop instead of on the handheld, it generally works better and gives you a heap more controllability. The sniper2 on my GTO, I threw the auto generated tune in the bin from the handheld and built my own using the laptop, it works so much better.

I'm gonna look into if I can do the full map on the FiTech with the pro tuning software. Years ago I was able to install and use the pro software, but I never used it for timing, just for data analysis and trends.

This engine used to eat up advance. I've dialed up to 40 total before when I used to race, with no pinging that I could tell. So now I am shooting for the rough equivalent of 34 total, adding some extra advance for high vacuum cruise. I am going more conservative these days since my performance needs have been reduced.
