Sure it does. The -91 trim flows 11% more than the -81. You may have the record for now, but I have no doubt someone running a -91 will be able to easily surpass your hp and torque curve
more air and less heat is going to make more power. I would say for now you probably have a superior tune than others with a stage 2
