Ok, Last night I went to dyno to play with the car...
Baseline = 233 whp/236 torque
After adjust AF a little bit
Tune = 246.7 whp/245.9 torque
I started to play with timing and advance 1 degree but for some reason the car started to knock after 5k rpms so I decided no to play this area.
Dyno run files are available if you want to see, those number are SAE with smoothing = 0 and conditions:
~85F, ~30 in-Hg, ~42% humidity
After I upload video I will added here.
