That's great advise.

First make sure that your vehicle is not binding in the transmission. Then tune the car until you feel you have the correct powerband, reminder, make sure the vehicle is up to normal operating temp before tuning. Once you feel you've got the tuning correct, adjust the 2 speed screw to enable second gear at 1/8th turns as previously suggested. Reminder, make sure your actually running in 1st gear... having cleaned up your vehicle, you may have made the transmission run more efficiantly, and therefore, the car runs in second gear immediatly due to the increased RPM's being delivered to the 2 speed system.

Good Luck
