This base flash allows you to leave the line at a predefined Boost level.
How it works,
if mph is = 0 and you have "boost defueling" set the truck will limit fueling up to the boost defuel setting until mph > 0 then it will allow for full fueling.
Example, if you want to leave the line at 10 psi of boost, you would set your boost defuel to 9 or 10 psi ( allow for some overhead). ensure your boost defuel is enabled.
1. Brake stand the truck and the quadzilla will only allow enough fuel for 10 psi of boost
2. lift off the brakes
3. as soon as mph > 0 then the quadzilla will allow full fuel.
