You're really not able to read JB4 logs? You're even manually emulating the same format to make your own lower resolution versions. So when I post things like "raised timing at the shift where boost drops", for example, you don't understand that I set timing to 20 degrees only for that moment that boost was down to 12psi? If you don't possess basic analysis skills here I wonder why you're continually chiming in the first place? Or are you just parroting John hoping that what he's saying is rational? My last two timeslip logs posted to refresh your memory.
Regarding your performance analysis, the big factors are DA (density altitude), a function of barometric pressure, air temperature, and humidity, and of course traction. My private track is around 900' elevation, 60-70F temperatures, normally has a DA of around 1500'.
On traction generally 60' time improvements knock 1.5x off your ET. So if I could get that 2.05 down to your 1.89, I expect to pickup 0.24ths. But generally speaking trap speeds are what tell you how well the modifications are working. And as John said back half trap gains are an easy way to evaluate power to weight.
Ignoring the slope differences I pickup 26.05mph in the back half, compared to your 23.97mph, so objectively speaking my car is a lot faster. And probably in worse DA, but also carrying less weight as you mention. But being faster isn't really the goal. The goal is to provide our customers with the best possible JB4 mapping. And since we're doing water/meth integration development right now with the best, safest, and fastest possible WMI implementation.
