Looks great,especially what AA tune did with the dip. Are you on the offroad tune? What options?

As far as SAE vs STD. isn't there a factor # to do the conversion?

If you get the data file, you can change the scale between STD and SAE in the Viewer software.

SAE was lower than STD by up to 8 hp on my dyno chart

EDIT: SAE factor conversion

As far as I read from another forum "STD is Another power correction standard determined by the SAE. Power is corrected to reference conditions of 29.92 InHg (103.3 kPa) of dry air and 60 F (15.5°C). Because the reference conditions include higher pressure and cooler air than the SAE standard, these corrected power numbers will always be about 4 % higher than the SAE power numbers. Friction torque is handled in the same way as in the SAE standard.""

So if mine was STD, it would be 198x1.04= 205.92 HP...So looks like you have roughly +5 HP?
Your max of 194 HP SAE *1.04 = 201.76 HP in STD
How does that compare to your STD result?
