What are your acceleration parameters set to? Sounds like you have them
set to values which, well, make things go slow.

Since it's anyone's guess what values were in your EEPROM (before Jetty 3.5)
where the acceleration parameters are stored, you may want to do a "Reset to factory defaults"
from RepG's Onboard Preferences. Also make sure that you are not using both firmware
deprime (set through Onboard Preferences) and SF's Reversal plugin (or Retraction in
Dimension).
