What are you attempting to do?
Just a little adjustment/caviot: Timing is not my issue; fuel is. The NA RTek can not tune for positive pressure (anything greater than 5 psi), as such fuel gets dumped into the engine down to 9-10:1 AFR at 3000RPM (when I'd actually begin to see positive pressure at partial throttle).
