I was able to open up the car this morning. With the 75% throttle valve I was able to reach 120mph before she pulled out of OD. That happens to be 75% of my gas pedal. Now with the Wide Open Throttle valve I could have held the pedal on the floor and it would have shifted into OD at 125mph and stayed in OD and top speed would probably have been around 150mph since 120mph came in at 3500rpms. I prefer the 75% valve since I dont do these high speed runs often.
